The intelligent co-pilot
Every number that decides whether this flip or build pays you
Most calculators stop at purchase price minus rehab. Real deals — renovations and ground-up builds — die in the details: the points, the draw schedule, the holding months, the comp that didn't support your ARV.
Know your all-in basis before you offer
Drop in the address, purchase or lot price and estimated ARV. Flip or ground-up build, the co-pilot returns your true cost basis in seconds so you never bid off a napkin again.
Rehab and hard-cost budgets that survive a GC
AI-assisted renovation and ground-up construction estimates scoped by property type, vintage, build spec and zip — then override any line item when your contractor says otherwise.
Carrying costs that stop eating your profit
Taxes, insurance, utilities and loan interest modeled month by month across a 4-month flip or a 14-month build, because every extra 30 days is real money off your check.
Price RTL and construction debt like the lender
Loan amount, rate, points, interest reserve, draw schedules, high-leverage and high-LTC structures — see exactly how financing terms move your Cash on Cash return.
Defend your ARV with local comps
Comparable sales analysis validates the resale number — including new-construction comps for spec builds — so your exit assumption is evidence, not enthusiasm.
Stress-test the deal in one drag
Scenario modeling shows what happens if the build runs 20% over, permits slip a quarter or the market softens 5% — before you're the one holding the keys.
AI risk assessment that says the quiet part
Thin margins, over-improvement for the block, entitlement and permit-heavy scopes, and construction timeline risk get flagged with a plain-English reason.
Reports your lender and partners take seriously
Generate a clean deal summary for capital partners, and run every project through a pipeline from lead to closing.
From address or empty lot to answer in four steps
01
Enter the property or lot
Address, purchase or land price, target ARV, and whether it's a renovation or a ground-up build. Public records fill in what they can so you stop retyping county data.
02
Let the co-pilot scope it
AI drafts the rehab or hard-cost construction budget — site work, shell, finishes, soft costs — plus carrying costs for that market. Override anything you know better.
03
Structure the capital stack
Model RTL or ground-up construction terms — high leverage, high loan-to-cost, draws, interest reserve, points and rate — and watch Cash on Cash move live.
04
Get the verdict
ROI, Cash on Cash ROI, profit margin and an AI risk read. Buy it, re-trade it, or walk — in minutes.
Stress-test the deal before you make an offer
Drag the numbers to see how purchase price, ARV and renovation costs change your ROI, cash-on-cash return and breakeven sale price in real time.

Flippers and builders who stopped guessing
“I killed two deals in my first week that my old spreadsheet said were winners. The carrying cost model caught what I was glossing over. That alone paid for a decade of subscription.”
Marcus Delgado
Principal, Ridgeline Property Group — 14 flips/yr, Phoenix
“I was skeptical of anything with 'AI' on the box. But the estimates landed within 6% of my GC's bid on three straight projects — two rehabs and a ground-up duplex — and I can override every line. It's a real underwriting tool.”
Sarah Kwan
Managing Partner, Harborlight Capital — Fix & Flip and ground-up, Charlotte
“My lender asked for the construction analysis in writing — draws, interest reserve, the whole stack. I exported the report, sent it, and had a term sheet at 88% LTC the next morning. Nobody takes a spreadsheet screenshot seriously.”
Jordan Rees
Owner, Rees Renovation Partners — RTL and construction borrower, Cleveland
