Where do the listings come from?

Listings come from licensed feeds (RentCast) enriched with the original listing copy via Realtor data. You can also add your own addresses or off-market properties.

How does Kavvl know creative financing is possible?

The listing text is parsed for signals such as owner or seller financing, subject-to, assumable mortgage and lease option. Only properties where this is verifiable show up; the rest stays hidden until proven otherwise.

How is the deal score built?

The 0-100 score combines cashflow, cash-on-cash, all-in percentage of ARV, creative finance signals, neighbourhood data from the US Census ACS and property condition.

How does Kavvl run the BRRRR numbers?

All-in equals purchase plus rehab plus closing plus holding costs including interest. Refinance is LTV times ARV, capped by a 1.20 DSCR requirement, minus refinance closing costs. With creative financing a down payment plus seller note is modelled instead of an all-cash purchase.

Can I send letters of intent?

Yes. Kavvl generates a letter of intent with your terms (down payment, rate, balloon, refinance option), emails it to the agent and tracks whether it was opened and answered.

Is this investment advice?

Underwriting BRRRR: from purchase to refinance

How to calculate all-in cost, ARV, the refinance amount and the cash left in a BRRRR deal.

All articles 5 min read · Updated 2026-06

BRRRR stands for buy, rehab, rent, refinance, repeat. The whole strategy hinges on two numbers: your all-in cost and the ARV, the value after rehab.

All-in cost

Purchase price plus rehab plus closing costs plus holding costs during the work (interest, taxes, insurance, utilities). Do not skip holding: three extra months of delay costs real money.

Estimating ARV

Use sold comparable properties in the same neighbourhood, ideally within six months and of similar size. Kavvl pulls those sold comps and derives a price per square foot.

The refinance

Lenders typically lend 75 to 80 percent of ARV and also test DSCR, usually at least 1.20. The lower of the two caps your new loan, minus refinance closing costs.

Is money left in the deal?

Subtract the new loan from your all-in cost. What remains is the cash left in, and that number drives your cash-on-cash return. If nothing is left, you can recycle the same capital.

Rule of thumb

All-in below 75 percent of ARV usually means you recover nearly all your capital on a normal refinance. Above 85 percent it gets tight.

In short

BRRRR is arithmetic, not luck. Get all-in and ARV right and the rest follows.
