The workflow

From address to answer in under a minute.

Enter any rental property address

Property data and rent estimates are pulled automatically from third-party market sources. No manual data entry required.

Get a full deal analysis, instantly

Cash flow, cap rate, cash-on-cash return, and DSCR calculated by deterministic code, not AI estimation.

Ask the AI to explain anything

A deal-specific AI agent can walk through any number, model a what-if scenario, or flag what to verify before you proceed.

Numbers you can trust

Calculations run on a deterministic engine. The same inputs always produce the same outputs. The AI explains - it never generates the math.

Assumptions front and center

Every estimated value is labeled with its source. Flagged inputs make it clear what to verify before committing to a deal.

What-if scenarios in seconds

Change the down payment, rent assumption, or interest rate and see the impact on cash flow and returns immediately.

For the BRRRR investor

Model the full cycle - not just the purchase.

Buy, Rehab, Rent, Refinance, Repeat. BRRRR is one of the most capital-efficient strategies in real estate - but only if the numbers work at every stage. Most deal analyzers stop at the purchase. DealPrism models the full cycle.

Enter your rehab budget and after-repair value, set your refinance terms, and see exactly how much capital you can recycle into your next deal - and whether the refi loan will actually qualify.

Two-state analysis

See acquisition and post-refi cash flow side by side. Know whether the deal works before and after refinancing.

Capital recycling output

DealPrism calculates how much capital remains in the deal after refi - or how much you pull out. The goal of BRRRR, made visible.

Refi qualification check

DSCR and LTV are flagged against lender thresholds so you know if the refi is likely to qualify before you are three months into a rehab.

BRRRR analysis is included with Active Investor.
