A 2026 comparison of 7 rental property calculators and tools (TrueCap, DealCheck, BiggerPockets and more) on free tier depth, pricing, mobile, and fit.

How we ranked these

The 7 tools below are ones we compared for searches like "best rental property calculator" or "rental analysis tool". Full disclosure: TrueCap is our tool, and we rank it first. If you just want a single metric fast, our free 1% rule calculator, mortgage payment calculator, and closing cost calculator each handle one piece of the underwrite with no signup. Ranking criteria, weighted roughly by impact on a typical solo investor:

  1. Free tier depth — can you actually underwrite a deal without paying? How many per month?
  2. Pricing — total cost for the calculator alone, not bundled with community or other services.
  3. Address auto-fill — does it pre-fill inputs like rent, rate, or tax from your address, or does it leave you to look everything up?
  4. Mobile UX — can you underwrite at a showing on your phone?
  5. Pro feature depth — cash-flow and equity projections, sensitivity, co-branded share links, PDF export.
  6. Audience fit — is the tool built for solo investors, scaling landlords, professional managers, or someone else?

The 7 calculators, ranked

TrueCap

#1 · Address-first screening plus paid decision tools

Deep dive

Pricing: Free core; paid Pro — see live pricing

Pros
  • +No-account preliminary screen with cap rate, CoC, DSCR, NOI, and monthly cash flow
  • +Editable HUD rent + FRED owner-occupied rate benchmarks, with manual local property tax
  • +Buy Box fit, with a Deal score
  • +Paid Pro plans add 10-year cash-flow and equity projections, sensitivity, Offer Ceiling, saved-deal comparison, and reports; see live pricing for current terms
  • +Lender-facing PDF + shareable read-only deal link with optional custom branding
Cons
  • −PWA, not native iOS/Android apps (DealCheck wins on pure mobile)
  • −Listing import is address-only — paste a Zillow/Redfin link and TrueCap pulls the address, not the listing's price, taxes or photos

Pick if: You want a no-account preliminary screen connected to a paid target, comparison, and reporting workflow.

DealCheck

#2 · Best mobile experience + best listing import

Deep dive

Pricing: Free Starter; Plus $10/mo and Pro $20/mo billed annually ($14 / $29 billed monthly), as of October 2026

Pros
Cons

Pick if: You underwrite on mobile at showings all day and want native apps.

BiggerPockets Calculator

#3 · Best if you already pay for BiggerPockets Pro

Deep dive

Pricing: Bundled with BiggerPockets Pro ~$390/year (~$32.50/mo)

Pros
Cons

Pick if: You're already paying for BiggerPockets for the community and the calculator is a bonus.

Mashvisor

#4 · Best for market discovery (heatmaps + neighborhood scoring)

Deep dive

Pricing: $39.99–$99.99/month billed annually ($49.99–$119.99 billed quarterly) for Lite, Standard and Professional; Enterprise is custom-priced (as of October 2026)

Pros
Cons

Pick if: You're picking which city or neighborhood to invest in next, not underwriting a specific property.

Stessa

#5 · Best acquisition-to-operations breadth

Deep dive

Pricing: Free Essentials plus paid Manage and Pro — see live pricing (reviewed 2026-08-27)

Pros
Cons
  • −Broader operations product rather than a narrowly focused acquisition decision workflow
  • −The official sources reviewed do not describe a target-derived Offer Ceiling
  • −Plan limits and marketplace terms should be checked on Stessa's live pages

Pick if: You want listing discovery and editable acquisition analysis to continue into accounting and landlord operations.

Excel / Google Sheets

#6 · Best if you've already invested time in a custom model

Deep dive

Pricing: Free (or your existing Office / Google Workspace subscription)

Pros
  • +Total control — model anything
  • +Free if you already have Office / Workspace
  • +Familiar to most investors with finance backgrounds
Cons
  • −Formula errors compound silently across every deal
  • −Large spreadsheets can be cumbersome on mobile
  • −No address auto-fill, no live data, no shareable read-only link
  • −Version drift kills collaboration with partners and lenders
  • −Maintenance cost over time is real — every market change requires manual updates

Pick if: You have a battle-tested model that handles your specific deal type (syndication waterfalls, custom debt structures) and don't need mobile.

Roofstock

#7 · Best for browsing listings with built-in projections

Deep dive

Pricing: Roofstock's retail property listings now route to Stessa's investment-property marketplace; check Stessa's live pages for current buyer terms

Pros
  • +Listings for individual investors now appear in Stessa's marketplace, powered by Roofstock
  • +Listings include built-in rent projections and comps, with projected cash flow, cap rate and ROI that recalculate from your own inputs
Cons

Pick if: You want to browse marketplace listings with projections built in. Pair with TrueCap to pressure-test the listing projection before offering.

Quick decision matrix

  • "I want address-first screening and an Offer Ceiling." Evaluate TrueCap's current free and Pro terms on the live pricing page.
  • "I want a no-account preliminary screen." TrueCap includes the core underwriting metrics before signup; complete-decision allowances and paid terms are shown on the live pricing page.
  • "I underwrite on my phone at every showing." DealCheck — native iOS / Android apps built for deal analysis.
  • "I already pay for BiggerPockets." Use their calculator — you're already there.
  • "I'm scouting which city to invest in." Mashvisor — heatmaps and neighborhood scores.
  • "I want listing discovery, acquisition analysis, and accounting in one product." Evaluate Stessa's current marketplace, underwriting, and plan terms.
  • "I want to browse listings with projections already built in." Roofstock (its listings now appear in Stessa's marketplace) — but pressure-test the listing projection in TrueCap before offering.
  • "I have a custom Excel model that works for my deals." Keep it — but consider TrueCap free as a sanity check on the formulas.
