TrueCap vs Rentometer: different tools, different jobs

Rentometer is a rent estimator — it tells you what a property should rent for based on local comps. TrueCap models the broader first-year rental economics from editable assumptions. They're not the same product; here's where each one fits.

TL;DR

Pick TrueCap if

  • You want a FULL deal underwrite — cap rate, CoC, DSCR, NCF, 10-yr projection.
  • You want to decide whether to buy, not just what rent to charge.
  • You want operating expense + mortgage + tax modeling included.
  • You want cash flow, returns, and selected-rule fit for each property.
  • You want unlimited free analyses.

Use Rentometer if

  • You ONLY need a quick rent comp — and already have a deal model elsewhere.
  • You're a property manager checking comp prices for a rent renewal.
  • You need deeper comp data beyond HUD's Fair Market Rent.
  • You want a quick second-opinion rent estimate alongside your other tools.

Honest take: they're complementary. Many investors use Rentometer for rent comp and TrueCap for the full deal underwrite. That's fine.

A rent number only matters once it flows into returns. Drop your Rentometer comp into the standalone cash-on-cash return calculator or cap rate calculator to see what that rent actually earns.

Common questions about TrueCap vs Rentometer

Quick answers to the questions investors comparison-shopping these tools actually ask.

Is TrueCap an alternative to Rentometer?
Not exactly — they solve different problems. Rentometer specializes in rent estimates pulled from rental-listing comps. TrueCap is a full underwriting calculator that starts from an editable HUD Fair Market Rent area benchmark and runs the downstream math (cap rate, CoC, DSCR, cash flow). If you want a tight rent estimate from active listings, Rentometer can complement the underwrite. Verify either source with property-specific evidence.
Does TrueCap give me a rent estimate like Rentometer?
Yes — TrueCap pre-fills rent using an editable HUD Fair Market Rent area benchmark for the relevant bedroom count. It is a housing-program benchmark, not a property-specific rent opinion or lender approval input. Rentometer's listing-based comps can provide a separate source to evaluate.
What's the difference between HUD FMR and Rentometer?
HUD Fair Market Rent is a government-published estimate of 40th-percentile gross rent for standard-quality units within HUD-defined areas. Rentometer uses rental-listing comps and shows a comp range. They answer different questions, and neither replaces subject-property lease evidence or local diligence.
Can I use Rentometer's rent in TrueCap?
Yes — every input in TrueCap is editable. If you trust Rentometer's comp for a specific neighborhood, type that number into the rent field and the rest of the analysis updates instantly. TrueCap pre-fills the HUD figure as a starting point, not a hard requirement.
Do I need both Rentometer and TrueCap?
It depends on the evidence available for the property. TrueCap provides the underwriting model and an editable HUD area benchmark; Rentometer can add listing-based comp context. Use the sources that fit the property, verify them independently, and sensitivity-test a reasonable rent range.

Sources & methodology: Feature and pricing rows reflect Rentometer's publicly listed information, last reviewed June 2026. Vendors change features and prices often — verify current details on Rentometer's own site. Where TrueCap claims “sourced defaults,” that refers specifically to auto-filled HUD Fair Market Rent, the FRED 30-year mortgage rate, and state average effective property tax — not a general claim about property-data import, which several of these tools also offer.

On price, plainly

Tools in this space run from free to well above TrueCap — check Rentometer's live pricing for their current number. What TrueCap's price buys is the decision layer, not more calculation: an Offer Ceiling under your selected targets, rule-fit results for your Buy Box with reasons, the downside stress test, and assumptions that are source-labeled instead of silently defaulted. Whether that workflow justifies the price depends on your volume, verification process, and existing tools.
