Analyze Your Investment Property

Type an address — we fill your assumptions. Add price and beds.

Strategy

Long-term rental acquisition is the core workflow. Other models stay available with their limitations attached.

BRRRR, flip, wholesale, and STR are screening aids. Their rehab, ARV, lender, operating, regulatory, and exit assumptions require separate evidence.

Where's the deal?

What does it cost?

What does it earn?

Add bedrooms to auto-estimate rent (HUD area data).

The expensive mistake

Nobody loses money on the spreadsheet. They lose it at the offer.

Overpaying by even 3% on a $250,000 rental is $7,500 gone before you collect a dollar of rent — and negative cash flow compounds it every month after. The protection isn't more metrics; it's knowing your walk-away price before you negotiate. That's the number TrueCap computes.

The decision gap

The problem isn't calculating the deal. It's deciding what to do next.

Should you pursue it? What price makes it work? What happens if the assumptions change? TrueCap connects those questions in one workflow.

  1. Analyze

    Start with an address

    Rent, mortgage rate and property tax auto-fill from HUD, FRED and your state's rates. Financing, vacancy and every expense stay yours to change — nothing is hidden or hard-coded.

  2. Decide

    See the real economics

    Cash flow, cap rate, cash-on-cash and DSCR, plus a 0-100 Deal Score and a plain-English verdict that says what the numbers mean, not just what they are.

  3. Offer

    Know your number

    TrueCap reverse-solves the highest price that still hits your targets. Don't buy at $325,000 because it's listed there. Offer $283,000 because that's where the deal works.

Common questions

The questions every investor asks first.

Why not just use a free calculator?

Free calculators — including TrueCap's own free analyzer — give you metrics: cap rate, cash flow, DSCR. What they don't give you is a decision. The Deal Decision Pack and Pro add the decision layer: the exact maximum offer that still hits your targets, a pass/fail against your own Buy Box with reasons, the downside stress test, and a report you can hand a lender. Metrics tell you about the deal; the decision layer tells you what to do.

How accurate is the auto-fill?

Rent starts from a HUD area benchmark (ZIP-level when available, otherwise county-level), not a property-specific rent comp. The rate starts from FRED's national owner-occupied 30-year benchmark, not an investor lender quote. Property tax uses a state effective-rate estimate. Every field is editable - replace screening defaults with local comps, the actual tax bill, insurance, and written loan terms before making an offer.

Why does Pro cost more than other rental calculators?

Because you're not buying analysis — you're buying the decision layer. Cheaper tools calculate the deal you describe; Pro computes your walk-away price on every deal, checks it against your Buy Box, and stress-tests the downside before the bank does. Overpaying by even 3% on a $250,000 rental costs $7,500 — one avoided mistake covers years of Pro.

Is TrueCap really free?

Yes. The cash-flow analyzer - cap rate, CoC, DSCR, monthly cash flow, address auto-fill, the 0-100 Deal Score, and a plain-English verdict - is free forever and unlimited. No card required. Free even saves up to 5 deals. Pro adds editing + unlimited saved deals, compare deals, Deal Decision Pack PDFs, a personal buy box (your criteria, checked on every deal), and the advanced modules (BRRRR + Fix-and-Flip, Sensitivity, 10-year projections, illustrative tax impact, and modeled exit comparisons).

Do I need a credit card?

No. The free analyzer needs zero signup and zero card - type an address and go. You only create an account if you want to save deals or unlock Pro.

Can I edit the assumptions?

Yes - every number is editable. TrueCap pre-fills rent, rate, tax, and expense defaults so you get an instant first pass, then you can change financing, expenses, and growth assumptions under “Improve accuracy” and rerun in a click.

What do I get with a Deal Decision Pack?

A complete one-property decision report: deterministic Max Offer, Deal Doctor rent/rate thresholds, assumptions, verdict, cash flow, cap rate, DSCR, downside scenario, 10-year projection, illustrative tax impact, modeled exit comparisons, and Deal Score. No account or subscription.

When should I upgrade to Pro?

Use Free to screen unlimited deals. Use a Deal Decision Pack when you need Max Offer and the complete decision report for one property without a subscription. Upgrade to Pro for an interactive Max Offer workflow, Buy Box screening, downside testing, unlimited saves, comparisons, reusable assumptions, branded reports, and unlimited exports. Pro is month-to-month - cancel anytime.

How does the Pro trial work?

Stripe collects a card at checkout. New subscribers get full Pro access for 14 days, and you can cancel online anytime. Subscription billing starts after the trial unless you cancel first. Returning subscribers start paid access immediately and are not eligible for another free trial.

Does this work for BRRRR or fix-and-flip deals?

Yes. Pro includes the BRRRR analyzer (cash-out refi math, post-refi cash flow, infinite-return alerts), the Fix-and-Flip analyzer (net profit, ROI, annualized ROI, break-even ARV), and the Rehab Cost Estimator (sq-ft-based defaults for every common work item).

Is this financial advice?

No. TrueCap surfaces the math you'd compute yourself - accurate formulas and market-data defaults - but every assumption is editable and the decision is yours. It's a calculator, not a financial advisor.
