Affordable Cost Segregation Companies for Properties Under $1 Million in 2026

Why Consider Affordable Cost Segregation Studies for Properties Under $1 Million?

Cost segregation identifies eligible shorter-life components instead of depreciating everything as a residential building. Residential rental buildings generally use 27.5-year depreciation under the general depreciation system; land is not depreciable. Eligible appliances, carpets, and certain land improvements can have shorter recovery periods. For 2026, 100% bonus depreciation-restored under current legislation-can apply to qualifying components that meet acquisition and placed-in-service rules, not the entire building. Your CPA should confirm eligibility and elections. The opportunity is larger deductions sooner, but an affordable study only makes sense when its timing benefits justify the total cost.

What Problems Make Cost Segregation Selection Difficult for Smaller Rentals?

• Starting prices may not fit your property. Confirm whether the quote applies to your purchase-price band, depreciable basis-the property cost eligible for depreciation-and property type.
• Study scopes differ. A DIY allocation model, remote expert review, and inspection-based engineering are not interchangeable. Ask who checks component classifications and supports the allocations.
• The fee may not cover everything. Confirm what audit assistance includes and ask your CPA about additional tax-preparation costs before comparing totals.
• Deductions may not be usable immediately. Passive-activity and at-risk rules can limit rental losses. Deductions may be suspended for later use rather than reduce current salary income.

Our tiered approach matches scope to budget and complexity. MVO’s sister brand, Cost Seg EZ, powers our DIY Study and Engineer Reviewed study options. Our Fully Engineered study includes an engineer-led virtual or in-person inspection and Lifetime Audit Protection. A lower fee alone does not establish value. For very small rentals, compare usable incremental deductions and their timing against study and tax-preparation costs; there is no universal minimum purchase price that makes a study worthwhile.

How Can Rental Investors Match an Affordable Cost Segregation Study to Their Property?

The right study is not necessarily the cheapest report. It is the least expensive option that fits your property's complexity and your need for review and support. At MVO Cost Segregation, we offer a choice of service depth, from standardized analysis through MVO's sister brand, Cost Seg EZ, to our Fully Engineered studies. That gives you an upgrade path when inexpensive standardized analysis is not appropriate. Use these six selection scenarios to narrow your options, then ask your CPA whether the accelerated deductions would be usable in your situation.

1. Minimize Upfront Fees for a Straightforward Rental

   If your rental meets the eligibility requirements and has minimal renovations, consider the lowest-cost entry point. DIY analysis uses structured allocation models rather than the asset-level documentation of a Fully Engineered study.

   • Cost Seg EZ DIY Study: From $595 for residential properties excluding condos, with depreciable basis below $1 million and renovations below $10,000.
2. Add Individual Engineer Review Within a Smaller Budget

   If you want an engineer to review your property's analysis without moving to a Fully Engineered study, consider the next service level. Keep the study fee and optional protection separate when comparing total costs.

   • Cost Seg EZ Engineer Reviewed study: From $895 for residential properties with depreciable basis below $1 million and renovations below $100,000. Includes detailed engineer review, with founder Andrew Kohrs reviewing every report before delivery.
   • Optional audit protection: Available separately for $195. Do not assume it includes the Lifetime Audit Protection attached to Fully Engineered studies.
3. Address Complex Assets or Substantial Renovations

   If substantial renovations or unusual assets make standardized allocation a poor fit, a Fully Engineered study is the safer choice for detailed analysis. A low purchase price alone does not make a property simple.

   • MVO Fully Engineered study: From $2,250, depending on complexity, with a virtual or in-person site inspection. Available for any property type or basis, using asset-level analysis and actual documentation.
4. Compare Audit-Support Commitments Before Purchasing

   Compare what protection is included, what costs extra, and the terms of that support. Our service levels do not carry identical commitments, and audit protection does not promise a particular IRS outcome.

   • DIY Study protection: Optional audit protection is available as an add-on.
   • Engineer Reviewed protection: Optional audit protection is available separately.
   • Fully Engineered protection: Lifetime Audit Protection is included.
5. Evaluate a Short-Term Rental With Professional Tax Input

   Average customer use of seven days or less is an exception to the IRS rental-activity definition. It does not, by itself, establish nonpassive treatment. Material participation and other taxpayer-specific rules still matter, so involve your CPA before treating accelerated deductions as immediately usable.

   • Planning resource: Read our guide to cost segregation for short-term rentals as a starting point for that discussion.
6. Check Whether the Fee Fits the Expected Usable Benefit

   For a very small rental, there is no universal purchase-price cutoff that makes a study worthwhile. Compare the timing value of usable additional deductions against the study fee and tax-preparation costs, especially if passive-loss limitations could defer the benefit.

   • Property-specific starting point: Request a free cost segregation estimate.
   • Process resource: Review how cost segregation works with your CPA before selecting a service level.

Your decision should connect three things: property complexity, the depth of analysis you need, and when you can use the deductions. Start with an eligible lower-cost tier when it fits. Move to a Fully Engineered study when your property needs component-level documentation or you want included Lifetime Audit Protection. Our team can help you compare service levels; your CPA should evaluate the tax consequences. This document is for informational purposes only and does not constitute tax advice.

Which Are the Best Affordable Cost Segregation Companies for Properties Under $1 Million in 2026?

Our ranking is an editorial assessment of study depth, eligibility, pricing transparency, and support-not an ascending price list. Compare the service you receive, not just the advertised starting fee. Also check whether a provider’s threshold refers to purchase price or depreciable building basis excluding land.

1. MVO Cost Seg

At MVO Cost Segregation, we offer a choice of study depth rather than one product for every rental. Our sister brand, Cost Seg EZ, powers our DIY Study and Engineer Reviewed study for eligible residential properties below $1 million in depreciable basis. Our Fully Engineered study provides an inspection-based alternative when your property needs detailed asset-level analysis. These are different services: an instant DIY report uses structured allocation modeling, while detailed engineer review is a specific feature of the Engineer Reviewed tier. Choose the scope that fits your property and your CPA’s requirements.

• Key Features
  • Tiered study depth: Cost Seg EZ provides DIY Study and Engineer Reviewed options within our broader service lineup.
  • Named, credentialed review: Founder Andrew Kohrs, our Head of Engineering, personally reviews every report, including every Engineer Reviewed study. He spent more than a decade at KPMG, where he helped run its cost segregation practice. No other study under $1,000 in this comparison names who reviews it.
  • Inspection-based upgrade: Fully Engineered studies include an engineer-led virtual or in-person inspection.
• Under-$1-Million Rental Offerings
  • DIY Study: Straightforward residential rentals excluding condos, with basis below $1 million and renovations below $10,000.
  • Engineer Reviewed: Residential properties with basis below $1 million and renovations below $100,000; includes detailed engineer review, founder review before delivery, and delivery in 3-5 business days.
  • Fully Engineered: Complex properties or cases requiring detailed asset-level analysis, with no property-type or basis restriction.
• Pricing: DIY Study: $595. Engineer Reviewed: $895. Fully Engineered: from $2,250, depending on complexity. Optional audit protection costs $195 on each lower-cost tier; Fully Engineered includes Lifetime Audit Protection.
• Pros: Entry price below $600; an $895 Engineer Reviewed study with a named, credentialed reviewer; and an inspection-based upgrade path.
• Cons: Lower-tier eligibility is strict; DIY excludes condos. Audit protection costs extra on the lower-cost tiers. DIY allocation modeling is not equivalent to a Fully Engineered asset-level study.

We place MVO first because our lineup lets a small landlord choose an eligible lower-cost option without treating every property as a DIY candidate. For a straightforward rental, Cost Seg EZ offers an accessible starting point. For a property that needs closer review, our Engineer Reviewed study adds review by Andrew Kohrs for $895, and our Fully Engineered study adds an inspection. That range-not a claim that we always have the lowest fee-is our editorial rationale. Review our cost segregation services or request a free cost segregation estimate to discuss the appropriate scope before committing.

2. CostSegregation.com

CostSegregation.com offers self-guided software for properties with building basis up to $1.5 million, excluding land. Its method uses component-level quantity takeoffs and standardized construction estimates adjusted to user inputs. The FAQ also acknowledges that some quantities rely on ratios and estimates. A useful distinction is its included audit defense: a low-cost software report does not necessarily mean no support. However, it does not name who reviews an individual self-guided report. Confirm both the selected-basis fee and the review scope before comparing it with an engineer-reviewed service.

• Key Features
  • Self-guided component-level software with construction estimates adjusted to property inputs.
  • Included audit defense covering written Information Document Request responses and calls with auditors to explain the report.
• Under-$1-Million Rental Offerings
  • Its supported building-basis ceiling includes rentals below $1 million, subject to the software’s property requirements.
  • The FAQ distinguishes estimated quantities from more precise engineering analysis using client photographs.
• Pricing: $495 at $500,000 building basis, $675 at $750,000, and $950 at $990,000 in its current residential selector. At $750,000, its self-guided report costs more than our eligible $595 DIY Study; at $990,000, it also exceeds our $895 Engineer Reviewed fee. Compare the actual basis and engagement scope, not the $495 starting offer.
• Pros: Low observed fee and meaningful included audit-defense assistance.
• Cons: The fee increases with building basis. Its FAQ describes combining purchase basis and same-year renovation costs into a modeled estimate, and says the software is not built to handle properties already in service with later improvements on different dates. Confirm how your actual renovation components, dates, and records will be analyzed. A self-guided report does not name its reviewer.

3. Cost Seg Smart

Cost Seg Smart combines automated component-level estimates with quality-control checks and technical-team review of flagged reports. Most residential work is remote. Its pricing matrix separates single-family homes, short-term rentals, and condos from duplexes through fourplexes, making property type important to the quote. The published package includes CPA coordination and lifetime written audit support. It does not publish its founders or engineers, and its site states that not every report is reviewed by a CPA or licensed engineer.

• Key Features
  • Automated component estimates, technical QC, and review of flagged reports.
  • CPA coordination and lifetime written audit support.
• Under-$1-Million Rental Offerings
  • Published categories cover single-family homes, short-term rentals, condos, duplexes, triplexes, and fourplexes.
  • Pricing bands use purchase price, not depreciable basis.
• Pricing: Single-family/STR/condo: $495 below $300,000; $895 in the $300,000-$700,000 band; $995 in the $700,000-$1 million band. Duplex/triplex/fourplex: $995 below $300,000; $1,295 for $300,000-$700,000; $1,495 for $700,000-$1 million.
• Pros: Transparent property-specific bands, CPA coordination, and lifetime written audit support.
• Cons: The $495 starting fee does not apply to every small rental: a $400,000 single-family house falls in the published $895 band. In the $700,000-$1 million band, the $995 fee is $400 above our eligible DIY fee and $100 above Engineer Reviewed. Renovations under $100,000 are advertised as included with a building study; $100,000-$1 million of renovations adds $595. Work on a property already owned has separate renovation-study pricing. Confirm the written scope and total fee; Form 3115 preparation is separate, and no reviewer is named.

4. RentalWriteOff

RentalWriteOff advertises a flat-price, engineering-based remote study with expert review across several residential property types. Its listed coverage includes condos and small multifamily properties, alongside single-family homes and short-term rentals. The process analyzes appraisals or photographs and property data rather than relying on a stated universal site inspection. Standard delivery is two business days after complete intake. For landlords considering a look-back study, included Form 3115 preparation for eligible cases is worth comparing. It describes reports as expert-reviewed but does not name its reviewers, so confirm who signs your study and the audit-support terms.

• Key Features
  • Remote, engineering-based analysis with expert review.
  • Standard two-business-day delivery after complete intake; Form 3115 included for eligible look-back studies.
• Under-$1-Million Rental Offerings
  • Listed types include single-family homes, condos, townhouses, duplexes, triplexes, fourplexes, short-term rentals, and mobile homes.
  • Confirm property-specific acceptance and required intake documents before ordering.
• Pricing: $899 per property, advertised as a flat fee.
• Pros: Straightforward published pricing, quick standard delivery after complete intake, and Form 3115 inclusion for eligible look-back work.
• Cons: Reviewers and founders are not named; confirm who signs your study and the audit-support scope in the engagement terms.

5. R.E. Cost Seg

R.E. Cost Seg’s Rapid Report is a software-enhanced service with expert engineer review and no site visit. Its eligibility requirements make it a defined option for straightforward residential properties rather than a universal solution for everything below $1 million. Limits cover square footage, depreciable basis, renovation spending, and layout; multi-unit properties also need identical or substantially similar units. The package includes written audit responses about methodology, classifications, and conclusions. Published delivery can be as little as five business days, but that wording is not an unconditional turnaround guarantee.

• Key Features
  • Software-enhanced analysis with expert engineer review, performed without a site visit.
  • Written audit responses addressing the report’s methodology, classifications, and conclusions.
• Under-$1-Million Rental Offerings
  • Residential properties must be below 3,500 square feet, with depreciable basis $1.2 million or less and renovations $80,000 or less.
  • Layouts must be straightforward; multi-unit properties require identical or substantially similar units.
• Pricing: Rapid Report starts at $950. The optional Form 3115 CPA Support Package costs $600 per property.
• Pros: Explicit expert engineer review and defined written audit assistance.
• Cons: Size, renovation, layout, and unit-similarity restrictions can exclude otherwise small rentals. There is no site visit, the fastest advertised delivery is not guaranteed, and R.E. does not name who reviews Rapid Reports or list its engineers’ credentials.

6. Overline

Overline describes an engineer-reviewed process that uses satellite imagery and construction data, with personal sign-off by Matthew Gigantelli of its engineering and CPA partner, Modern CFO. Its residential pricing article provides separate benchmarks for condos and several other residential types. The service also includes CPA coordination and lifetime documentation and technical audit support. Its published standard process takes two to four weeks. Overline advertises 5+ years of specialized cost-segregation experience for Matthew Gigantelli, compared with the 25+ years of cost-segregation engineering experience our MVO team brings. At MVO, founder Andrew Kohrs personally reviews every report. For comparison purposes, the named reviewer is a useful distinction, but the reviewed service description does not establish an on-site inspection as a universal part of every engagement.

• Key Features
  • Engineer review using satellite imagery and construction data, with named personal sign-off.
  • CPA coordination plus lifetime documentation and technical audit support.
• Under-$1-Million Rental Offerings
  • Published residential benchmarks cover condos, standalone single-family homes, townhouses, ADUs, cabins, and two-to-four-unit properties.
  • Obtain a proposal confirming your property’s scope rather than treating a benchmark as a binding quote.
• Pricing: Provider-published benchmarks are $1,440 for a residential condo and $1,800 for the specified other residential types. These are not independently verified market averages.
• Pros: Named reviewer, CPA integration, and lifetime technical support.
• Cons: Published benchmarks exceed several entry-level options in this list. Current pricing requires confirmation, and an on-site inspection is not listed as standard.

7. Virtual Cost Segregation

Virtual Cost Segregation offers residential studies performed completely remotely by a US-based engineering team. Its advertised package combines component cost sources, renovation-document review, audit support, and Form 3115 catch-up service. Published delivery is three to five business days. Its fee is higher than the budget tiers covered here, but the bundled scope matters when comparing quotes that charge separately for look-back assistance or other services. Owners ordering several studies also have a published volume option. Confirm that the remote-only process fits the property’s documentation and inspection needs before engaging.

• Key Features
  • Completely remote work by a US-based engineering team.
  • Published scope includes component cost sources, renovation documents, audit support, and Form 3115 catch-up service.
• Under-$1-Million Rental Offerings
  • A published residential study package; confirm acceptance and scope for your specific rental.
  • A multi-study discount for owners ordering three or more studies.
• Pricing: $2,200 per residential study, or $1,980 each for three or more, reflecting the published 10% discount.
• Pros: Bundled scope, published three-to-five-business-day delivery, and a stated volume discount.
• Cons: Higher upfront fee than the entry-level options listed here. A remote-only process may not fit cases requiring an inspection.

Why Is MVO Cost Seg the Editorial First Choice for Affordable Studies Under $1 Million?

We rank MVO Cost Seg first because our Engineer Reviewed study pairs a sub-$1,000 price with a reviewer you can identify. For $895, every report is reviewed by founder Andrew Kohrs, who spent more than a decade at KPMG and helped run its cost segregation practice. No other study under $1,000 in this comparison names who reviews it. Through MVO’s sister brand, Cost Seg EZ, the DIY Study starts at $595, and our Fully Engineered study adds inspection-based analysis for complex properties. Another provider may quote a lower fee, so compare written scope, reviewer responsibility, and audit support, and ask your CPA about usable deductions. Request a free cost segregation estimate.
