Built by a lender, not a spreadsheet jockey

You're one bad budget away from building for free.

Purchase or lot price, ARV, rehab or hard-cost scope, carrying costs and RTL/construction loan terms rolled into one honest ROI number. No more 14-tab spreadsheet, no more optimism math.

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.

    Plan review in this jurisdiction averages 9 weeks; 1 in 3 projects sees a second-round correction.

  2. Site work & foundationWeeks 15–22Medium risk

    Wet-season pour window is tight — 3 weeks of weather float assumed in the schedule.

  3. Vertical & rough-inWeeks 23–40Medium risk

    Framing and MEP trade availability is the top slippage driver in the last 12 months of local permits.

    Final inspection to certificate of occupancy is averaging 11 days; 60-day marketing period modeled.

A 12-week overrun costs roughly $18,400 in additional interest, taxes and insurance — dropping the margin to 11.9%.

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.
