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 is a full rental underwriter that also estimates rent, plus everything else you need to decide whether to buy. They're not the same product; here's when each one wins.

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 a verdict (Strong / Decent / Skip) on 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 uses HUD Fair Market Rent as a rent baseline and runs all the downstream math (cap rate, CoC, DSCR, cash flow). If you want a tight rent estimate from active listings, Rentometer is still useful. If you want a complete underwrite from one address, TrueCap is enough on its own.
Does TrueCap give me a rent estimate like Rentometer?
Yes — TrueCap pre-fills rent using HUD's Fair Market Rent (county-level, broken down by bedroom count). It's an authoritative baseline rather than a comp-driven estimate, so you get something defensible to show a lender. For tight neighborhood-level comps in hot markets, Rentometer is still the more granular tool.
What's the difference between HUD FMR and Rentometer?
HUD Fair Market Rent is a government-published 40th-percentile rent for every county in the US, refreshed annually. It's what Section 8 vouchers use. Rentometer aggregates current rental listings and shows you a comp range. HUD is more conservative and defensible; Rentometer is more current and granular. Many investors use both: HUD for the underwrite, Rentometer for the listing-price decision.
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?
Most investors don't. TrueCap's HUD baseline is accurate enough for the underwriting decision in most markets. Where Rentometer earns its keep: hot markets where current listings significantly exceed FMR (you want the upside in your projection) or sub-market neighborhoods where county-level FMR is too coarse. Otherwise TrueCap alone covers the full job.

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.
