How DealPrism works, what it explains, and where you still need judgment
This hub groups the recurring product questions that otherwise get fragmented into thin standalone pages: assumptions, AI chat, subscriptions, deal comparison, and BRRRR analysis.

What is DealPrism?
DealPrism helps rental property investors understand the numbers behind a deal without building spreadsheets.
Example: a duplex might show $2,200 rent and a $1,400 mortgage, which looks like $800 profit. DealPrism includes vacancy, taxes, insurance, maintenance, management, and financing so you see a more realistic cash flow.
The product helps you move from a rough guess to a structured, numbers-based view.
Who is DealPrism for?
DealPrism is useful for both beginner and experienced investors.
Beginners use it to understand the meaning behind the numbers. Experienced investors use it to move faster, pressure-test assumptions, and compare opportunities with less manual work.
How does DealPrism estimate rent?
DealPrism uses available property and market inputs to estimate monthly rent, then lets you override that assumption when you have stronger local comp data.
The safest workflow is to treat the estimate as a starting point, then validate rent with neighborhood comps, a property manager, or your own underwriting.
Why should I customize assumptions?
Default assumptions help you get to an initial answer quickly, but the best analysis comes from inputs that reflect your actual plan.
If you know your lender quote, contractor estimate, or target rent, updating those values gives you a more realistic analysis.
What does the AI do versus the calculation engine?
The calculation engine handles the math. The AI explains the results.
The engine answers “what are the numbers?” The AI answers “what do the numbers mean?”
Can I trust AI answers inside DealPrism?
The AI should be grounded in the deal data and calculation results already on the page.
It is best to think of AI as an explanation layer, not a replacement for due diligence.
Does DealPrism give financial advice?
No. DealPrism provides educational analysis and decision support based on available data and user assumptions.
The app can help explain tradeoffs, but it does not replace lender guidance, tax advice, legal advice, or your own due diligence.
What subscription plans are available?
DealPrism offers multiple plan tiers with different access to analysis volume, saved deals, AI features, and billing options.
Plan details can change over time, so the billing and plans pages inside the app are the best place to confirm current availability and limits.
What is deal comparison in DealPrism?
Deal comparison lets you place two or more saved deals or scenarios side by side so you can compare key underwriting metrics in one view.
It is designed for the moments when the real question is not "what does this deal look like?" but "which version is better?"
In the comparison view, DealPrism shows:
- Side-by-side metrics for the selected deals or scenarios - An AI-generated summary of the most important differences - BRRRR-specific rows when one of the deals is in BRRRR mode
Deal comparison is available on Active Investor and Power Investor. Explorer does not include it.
What is BRRRR and how does DealPrism model it?
BRRRR stands for *Buy, Rehab, Rent, Refinance, Repeat*. It's a real estate investment strategy where you purchase a property that needs work, renovate it, place a tenant, refinance based on the improved value, and use the cash from the refinance to fund your next deal.
The appeal of BRRRR is *capital efficiency* - instead of leaving your down payment locked in one property indefinitely, you try to pull most or all of it back out through the refinance and deploy it again.
DealPrism models the full BRRRR cycle in two states:
Acquisition state - what the deal looks like when you purchase it, based on your down payment, loan terms, and initial rent assumptions.
Post-refinance state - what the deal looks like after rehab is complete, the property is rented, and you've refinanced at the new appraised value. DealPrism shows your updated cash flow, DSCR on the new loan, how much capital you've recycled out, and how much (if any) remains in the deal.
To use BRRRR analysis in DealPrism, you'll need to enter your rehab budget, your estimate of the property's after-repair value (ARV), and your expected refinance terms. DealPrism does not estimate ARV - that requires local comparable sales data, which you'll need to research or confirm with an appraiser or agent.
BRRRR analysis is available on the Active Investor plan and above.
