The best real estate investment analysis software
What separates a good deal from an expensive lesson? Usually the math you did before making the offer. Investment analysis software runs that math for you: cash flow, cap rates, ROI, rehab budgets, and rent projections. The eight tools below cover the full range, from quick deal calculators to deep market datasets.
Starting price$10/month
Free planYes
DealCheck is the leading property analysis platform for investors who want answers in seconds rather than spreadsheet sessions. Enter a purchase price, financing, rehab costs, and rent, and it calculates cash flow, cap rate, cash-on-cash, ROI, ROE, IRR, and long-term buy-and-hold projections up to 35 years. It also pulls up to 20 recent sales and rental comps per property and generates professional PDF reports.
The pricing is refreshingly straightforward: a free Starter plan covers up to 15 saved properties, Plus runs $10 per month, and Pro $20 per month, with a free 14-day trial on paid plans. With over 200,000 active users, it is the closest thing this category has to a standard. If you analyze deals regularly, start here.
What we like- Genuinely free starter plan
- Analyzes rentals, BRRRRs, flips, wholesale, and multifamily
- IOS and Android apps with nationwide comps
Watch out for- Free plan caps saved properties at 15
- Advanced features need Plus or Pro

PropStream is less a calculator and more the data engine behind your analysis. Its database covers more than 160 million property records, 308 million deeds and sales, and 70 million MLS records, searchable through 165+ filters and 20 pre-built lead lists for finding high-equity, absentee-owner, and pre-foreclosure properties. Recent additions include AI predictive property scores and enhanced valuation modeling.
The platform also bundles rehab and ADU calculators with ROI analysis, skip tracing, and marketing tools, so you can go from research to outreach in one workflow. A 7-day free trial is available. It is the best fit for investors whose strategy starts with finding off-market deals rather than analyzing listed ones.
What we like- 160M+ property records with 165+ filters
- AI-powered insights and predictive scores
- Built-in rehab and ADU calculators
Watch out for- Subscription plus add-on fees can add up
- Learning curve for new users

Stessa
Best for: rental accounting and portfolio performance tracking
Visit stessa.com
Starting priceSee website
Free planYes
Stessa answers the question every landlord asks at tax time: how did my properties actually perform? The platform offers free property management software for landlords with automated income and expense tracking, bank account integration, rent collection, and investor-ready financial reports. Everything updates in real time as transactions post.
Founded in 2016, it has become the default free accounting layer for small-portfolio landlords. It will not underwrite your next purchase, which is why it pairs so well with DealCheck or PropStream on this list. Use Stessa to measure what you own, and an analysis tool to decide what to buy next.
What we like- Free core platform for landlords
- Automated bookkeeping with bank integration
- Tax-ready financial reports
Watch out for- Focused on owned rentals, not deal analysis
- Advanced features cost extra
Starting priceSee website
Free planFree trial (7 days)
Mashvisor's signature move is letting you evaluate any property under two strategies at once: traditional long-term rental or Airbnb short-term rental. The platform shows cap rate, cash-on-cash return, cash flow, and occupancy for each, with heatmaps that let you scan whole cities for neighborhoods meeting your criteria. It claims to compress months of market research into minutes.
Founded in 2014, the company has added a real estate data API and a partnership with Redfin for more transparent market data. A 7-day free trial is available. For investors deciding between long-term and short-term strategies in a given market, nothing else on this list makes the comparison this directly.
What we like- Side-by-side Airbnb vs. traditional rental analytics
- Heatmaps for market scanning
- Redfin data partnership
Watch out for- Data quality varies by market
- Best features sit on higher tiers

AirDNA
Best for: short-term rental market research and revenue data
Visit airdna.co
Starting priceSee website
Free planYes
AirDNA is the industry-standard dataset for short-term rental performance, tracking more than 10 million listings on Airbnb, Vrbo, and Booking.com across 120,000 markets worldwide. Investors use it to check occupancy rates, average daily rates, revenue per listing, and its proprietary Market Score before buying a vacation rental, plus zoning data showing whether STRs are even legal in a given area.
The company recently launched Adapt, an AI-native revenue management system for STR operators that is free to connect. Free market data pages cover many markets, with paid tiers opening up deeper research. If short-term rentals are your strategy, AirDNA is the data source your analysis should start from.
What we like- Tracks 10M+ STR listings across 120,000+ markets
- Market Score, ADR, occupancy, and RevPAR data
- Free market pages
Watch out for- Full market research requires paid tiers
- Focused exclusively on short-term rentals
Starting priceSee website
Free planYes
RentCast gives you instant answers to the two questions behind every rental analysis: what is it worth, and what will it rent for? Its database covers over 140 million properties with 500,000 records updated daily, producing automated value and long-term rent estimates with visible ranges and the exact comps used. Market data spans more than 38,000 zip codes, and you can download PDF reports or share interactive links.
You can start using it free online, with upgrades for larger portfolios, and a property data API serves developers building real estate applications. It evolved from the RealtyMole API, so the data infrastructure is mature. Use it to sanity-check rents and values before running full underwriting elsewhere.
What we like- Free online use with AVM value and rent estimates
- 140M+ properties and 38K+ zip codes
- Developer API available
Watch out for- Upgrade pricing not published on the homepage
- Estimates are only as good as local comp data
Starting priceSee website
Free planYes
Rehab Valuator is built for one job: telling a flipper or wholesaler exactly what they can afford to pay. It estimates repair costs, projects investor returns, analyzes financing options, and produces professional reports designed to win over lenders and partners. The workflow is deliberately fast, because wholesale deals do not wait for pretty software.
A free Lite tier lets new investors try the core analysis before committing to a subscription, and the company provides webinars and tutorials for learning the strategies behind the numbers. If your strategy is fix-and-flip or wholesaling, this is more focused than the generalist tools above.
What we like- Fast MAO and ARV calculations
- Repair cost and financing analysis
- Professional lender-ready reports
Watch out for- Utilitarian interface
- Focused on flips rather than buy-and-hold rentals
Starting priceSee website
Free planYes
FlipperForce covers the entire flip lifecycle, not just the analysis. The deal analysis side includes flip and BRRRR analyzers, a rehab estimator, comps for ARV forecasting, and investment reports. Once you buy, the same platform manages the project: schedules, tasks, budgets, expense tracking by vendor, photo logs, and an AI receipt analyzer.
Founded in 2018, it offers a free Rookie plan for new investors evaluating their first deals, with Solo and Team plans scaling up to full project management and accounting. If you want one system from first walkthrough to final sale, FlipperForce is the most complete option here.
What we like- Deal analysis, project management, and accounting in one platform
- Free Rookie plan
- Rehab estimator and comp tools
Watch out for- Web-first with mobile apps still maturing
- Full power needs the paid all-in-one plans
The numbers that matter: cap rate, cash-on-cash, and IRR in plain English
Every tool above reports these metrics, and they are worth understanding before you trust any of them. Cap rate is the property's annual net operating income divided by its price: it measures the asset itself, ignoring your financing. Cash-on-cash return divides your annual cash flow by the cash you actually invested, so it reflects your mortgage and debt. IRR, the internal rate of return, accounts for the time value of money across the whole hold period including the eventual sale.
No single metric tells the whole story. A high cap rate with negative cash flow after debt service is a bad deal wearing good makeup. Run all three, stress-test your rent and vacancy assumptions, and never let a tool's default appreciation rate do your thinking for you.
How to pick real estate analysis software for your strategy
Match the tool to what you actually do. Buy-and-hold landlords need rental calculators with long-term projections and portfolio accounting, which points to DealCheck plus Stessa. Flippers need MAO, ARV, and rehab estimating, which points to Rehab Valuator or FlipperForce. Short-term rental investors need occupancy and revenue data, which means AirDNA or Mashvisor. Data-first investors who hunt off-market deals need PropStream or RentCast underneath everything.
Check the data behind the estimates
Every automated valuation and rent estimate is only as good as its comps. Favor tools that show you the actual comparable properties and let you adjust them. A black-box number you cannot inspect is not analysis; it is a guess with good branding.
Mind the free tier limits
Free plans in this category are genuinely useful but capped: DealCheck limits saved properties, AirDNA limits market depth, and RentCast limits portfolio size. Map your deal volume against those caps before committing your workflow to a free tier you will outgrow in a month.
Verify numbers independently before offering
Software accelerates analysis; it does not replace diligence. Verify rents against live listings, confirm rehab costs with a contractor walkthrough, and check ARV against an agent's CMA before you make an offer. The investors who get burned are the ones who trusted the calculator and skipped the verification.
How we chose
We compared real estate investment analysis tools against the needs of US investors across buy-and-hold, flip, BRRRR, wholesale, and short-term rental strategies, reviewing vendor documentation and pricing pages, feature coverage for underwriting and market data, and public reviews on G2, Capterra, BiggerPockets, and Reddit. We included both pure analysis tools and the data platforms that feed them, and we favored tools with free tiers or trials so readers can verify value before paying. Pricing was confirmed on vendor pricing pages where published. We did not test any of these tools hands-on.
Frequently asked questions
What is real estate investment analysis software?
It is software that runs the financial math on investment properties: cash flow, cap rates, ROI, rehab budgets, rent estimates, and long-term projections. It helps investors decide whether a deal works before making an offer.
How much does real estate investment analysis software cost?
Many tools offer free tiers or trials. Paid plans typically range from $10 to $100 per month for analysis tools, with data-heavy platforms like PropStream priced higher. Always check the vendor's current pricing page.
Can I analyze rental properties for free?
Yes. DealCheck, Stessa, RentCast, Rehab Valuator, and FlipperForce all offer free plans or tiers, and PropStream and Mashvisor offer free trials. Free tiers usually cap the number of properties or depth of data.
What is the difference between cap rate and cash-on-cash return?
Cap rate measures the property's net operating income relative to its price, ignoring financing. Cash-on-cash return measures your annual cash flow relative to the cash you invested, so it reflects your mortgage and debt.
Which tool is best for Airbnb investment analysis?
AirDNA provides the deepest short-term rental market data, while Mashvisor lets you compare Airbnb versus long-term rental returns side by side for the same property. Many STR investors use both.
Do I still need a real estate agent if I use analysis software?
Yes. Software handles the numbers, but agents provide on-the-ground comps, negotiation, and local knowledge that no dataset captures. Use analysis tools to screen deals, then verify with a professional before offering.
