The math isn't AI.

DealPrism does not use AI to invent investment numbers. Every calculation runs through a fixed financial formula system using property data, financing assumptions, and market estimates. AI only helps explain the results in plain English.

How it works

See how a rental property analysis comes together before you commit.

New to rental property investing? DealPrism walks you through the important numbers in plain English, so you can understand what the property may earn, what it may cost, and where the risk may be before you make a decision.

Enter a property address

You can start with just the address. DealPrism builds the first draft of the deal for you, so you are not stuck starting from a blank spreadsheet.

Review the first pass of the numbers

DealPrism estimates rent, taxes, financing, and operating costs so you can get a realistic starting point quickly and adjust anything that looks off.

See what the deal looks like

Review monthly cash flow, property-level return, return on the cash you would invest, and whether the rent appears to cover the mortgage comfortably, with plain-English explanations throughout.

Adjust the assumptions and compare outcomes

Change the rent, financing, or expenses anytime and watch the analysis update. The math stays consistent, so you can see exactly which assumption changed the result.

Why DealPrism

Trust starts with knowing what is calculating the deal.

Most first-time investors are not looking for black-box AI. They want transparent formulas, visible assumptions, and help understanding what the numbers mean before they risk real money.

The calculation engine handles the math

DealPrism does not use AI to invent investment numbers. The same inputs always produce the same result because the analysis runs through fixed formulas.

AI explains the numbers, not the decision

Ask what DSCR means, why cash flow changed, or which assumptions are affecting the result. The AI helps interpret the analysis in plain English but never changes the result.

Data sources stay visible

Property records, rent estimates, defaults, and market assumptions are surfaced so you know what came from data, what was estimated, and what should be verified.

Analyze your next rental property in under a minute.

Start with deterministic analysis, scenario modeling, and AI explanations tied to the actual deal.
