When to Refinance in a BRRRR: Seasoning, Appraisals, and the 75% LTV Rule

You bought at $120K. You put $150K into the rehab. The ARV — after-repair value — is $190K. You're running a BRRRR: Buy, Rehab, Rent, Refinance, Repeat. The refinance is where you pull your cash back out. Get it right, and you're into the next deal with little or no money left in the property. Get it wrong, and you're stuck with capital tied up or worse — an appraisal that comes in low.

Here's when to refinance, what lenders want, and how the 75% LTV rule actually works with real numbers.

The Seasoning Period: 6–12 Months

Most lenders won't do a cash-out refinance on a property you've owned for less than six months. Some want twelve. The seasoning period exists to prevent flip-and-refi schemes — buy, cosmetic rehab, refi at inflated value, walk with cash. Lenders have been burned. They want to see that you've held the property, that it's stabilized, that the value is real.

So plan for it. If you close on the purchase in March, don't expect to refi before September. If your lender wants twelve months, you're waiting until next March. During that time, you're paying the bridge loan or hard money. Factor that into your deal math. A 12-month hold at 12% on $200K drawn is $24,000 in interest. That eats into your margin. Buy deals that can absorb it. Some investors use a "blended" rate calculation — they add the holding cost to their all-in number and recalculate whether the deal still works. If $24K in interest pushes your effective cost from $140K to $164K, does 75% of ARV still cover it? If not, you need a bigger discount at the buy.

How the Appraisal Works

The refinance lender will order an appraisal. The appraiser looks at comparable sales — similar properties that sold recently in the area. They adjust for size, condition, and features. Your rehab matters. A fully renovated unit with new HVAC, updated kitchen, and fresh paint will comp higher than a dated one. Provide the appraiser with your rehab scope and receipts. Some appraisers give more weight to documented improvements.

The appraisal determines the value the lender uses for LTV. If it comes in at $185K instead of your projected $190K, your max loan drops. At 75% LTV, $185K means $138,750 max loan. At $190K, it's $142,500. That $4,750 difference might be the gap between pulling most of your cash out and leaving money in the deal. Get the appraisal right. Use strong comps. Don't over-improve for the neighborhood — you won't get dollar-for-dollar back. I've seen investors put $80K into a rehab in a $150K neighborhood. The appraiser said the property was worth $175K — not $230K. The improvements were nice. They just didn't move the needle in that market. Match your rehab to the comps. Don't out-improve the block.

Cash-Out vs Rate-and-Term

A cash-out refinance does two things: pays off your existing loan (hard money, bridge) and gives you additional proceeds based on the new value. You're pulling equity. A rate-and-term refi just replaces the existing loan — same balance, better rate. No equity extraction.

For BRRRR, you want cash-out. You're replacing expensive short-term debt with long-term conventional (or DSCR) and taking the difference in cash. That cash goes into the next deal.

The 75% LTV Rule: What It Means for Your Deal

Most cash-out lenders cap at 75% of appraised value. Some go to 80% for strong borrowers. Plan for 75% to be safe.

Your deal: Purchase $120K. Rehab $150K. Total in: $270K. ARV $190K. At 75% LTV on $190K, max loan = $142,500.

Your payoff: Hard money balance — let's say you drew $250K (purchase + most of rehab). You need to pay that off. $142,500 doesn't cover $250K. You've got a shortfall. That's the problem.

The fix: You need to buy and rehab for less than 75% of ARV. If ARV is $190K, your all-in cost needs to be under $142,500 to pull everything out. At $270K all-in, you're leaving $127,500 in the deal. That's not a BRRRR — that's a buy-and-hold with a refi.

A deal that works: Purchase $80K. Rehab $60K. Total in: $140K. ARV $200K. At 75% LTV: $150K max loan. You pay off $140K in debt, pull $10K out. You're into the next deal with cash back. The spread between your cost and 75% of ARV is your margin. Get it wrong, and the refi doesn't rescue you.

One more wrinkle: some lenders use the lower of purchase price plus improvements or appraised value when sizing the loan. So even if the appraisal comes in at $200K, they might cap your loan based on your documented cost. Read the guidelines. Know your lender's rules before you close the purchase. The last thing you want is a surprise at the refi table.

When to Pull the Trigger

Once you've hit the seasoning period and the property is rented, order the refi. Don't wait for rates to drop — you're paying bridge interest every month. Refi as soon as you're eligible. If the appraisal comes in low, you've got options: hold longer and try again, put more money in and refi later, or accept leaving some capital in the deal. But the goal is to get out as much as you can, as soon as you can.

What If the Appraisal Comes In Low?

It happens. You expected $190K. The appraiser says $175K. At 75% LTV, that's $131,250 max loan — $11,250 less than you planned. You've got three choices: bring cash to the table to pay off the shortfall, hold the hard money longer and try a different lender or appraiser in a few months, or accept leaving more in the deal. The best defense is buying with enough spread that a 5–8% appraisal miss doesn't kill you. If you need $190K to make it work, you're one bad comp away from trouble. Build in cushion.

A final note on timing: rates move. If you're six months into your hold and rates have dropped half a point, you might refi early. Some lenders allow it. Others don't. If rates have risen, you're stuck with the higher payment. You can't time the market perfectly. But you can build enough spread into your deal that a 0.5% rate move doesn't kill the refi. That's the real skill — building in margin for the things you can't control.

The BRRRR Strategy guide covers the full cycle — from finding the right purchase to ARV analysis to seasoning and refinance. Get the math right at the buy. The refi is just the exit.
