TrueCap vs Rentometer: different tools, different jobs
By TrueCap · built by a Philadelphia rental investor
Rentometer starts from rent: an estimate for an address built on nearby rental comps, plus a Deal Worksheet on its Pro plan that turns that rent into cash flow and cash-on-cash return. TrueCap starts from the purchase decision: first-year rental economics from editable assumptions, with rent as one input you replace. Here's where each one fits.

Common questions about TrueCap vs Rentometer
Quick answers to the questions investors comparison-shopping these tools actually ask.
Is TrueCap an alternative to Rentometer?
They overlap in part. Rentometer specializes in rent estimates built from recent nearby rental comps, and its Pro plan adds a Deal Worksheet for cash flow and cash-on-cash return. TrueCap is a full underwriting calculator that starts from an editable HUD rent benchmark and runs the downstream math (cap rate, CoC, DSCR, cash flow). If you want a rent estimate from nearby comps, Rentometer can complement the underwrite. Verify either source with property-specific evidence.
Does TrueCap give me a rent estimate like Rentometer?
Not by default. TrueCap pre-fills rent using an editable HUD rent benchmark for the relevant bedroom count: ZIP-level when available, otherwise the HUD Fair Market Rent area; when an address has no county match, a statewide HUD figure, labeled as such. It is a housing-program benchmark, not a property-specific rent opinion or lender approval input. The optional comps lookup (one free lookup; Pro includes up to 50 per month) adds a rent estimate from nearby properties. Rentometer's comp-based estimates 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 builds its estimate from recent nearby rental comps and reports an average and a median. 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 rent benchmark; Rentometer can add comp-based rent context. Use the sources that fit the property, verify them independently, and sensitivity-test a reasonable rent range.
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 for your targets, Buy Box fit 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.
