Fix and Flip Buy Box: Flood Zones, ARV Caps, MLS Offers

A workable fix and flip buy box is narrower than most people think. Frank Brown, a Tampa concrete contractor who turned two flips in 2023 into 22 in 2024, screens for a single set of physical and financial criteria: after-repair value under $400,000, under 1,500 square feet, 3/2 or 2/2, single story, block construction where he can get it, Flood Zone X only, and no sinkhole remediation or visible settlement.

Those filters exist for a reason, and the reasons are arithmetic, not preference. A $200 to $300 monthly flood insurance premium is invisible on a million-dollar house and fatal on a $280,000 one. An ARV above $400,000 starts knocking out loan products and shrinking the exit pool.

Below: the full screen, the deal-killers, the exact text package Brown sends listing agents to beat the VA swarm on fresh MLS listings, why he paid a $60,000 assignment fee without blinking, and the cash reserve he says you should not start without.

The Buy Box: What Actually Gets Screened In

Frank Brown’s fix and flip buy box starts with the exit, not the entry. He keeps ARV under $400,000 specifically so the finished house qualifies for every loan vehicle a retail buyer might bring — which keeps the buyer pool as large as possible in a Florida metro with a well-documented affordable housing squeeze.

Everything else in the filter follows from that ceiling:

• Under 1,500 square feet. Keeps rehab scope and ARV both inside the band.
• 3/2 or 2/2. The configurations that move fastest at that price point.
• Single story. Simpler rehab, broader buyer appeal.
• Block construction, ideally. A preference, not a hard rule.
• Flow of the house. This is the one most investors skip.

“Flow” is Brown’s term for whether the floor plan works as a home, and he applies it before he runs numbers. His specific example: if the only way to the backyard is through a bedroom, he walks. No amount of finish work fixes a layout that makes a buyer hesitate at the showing, and at a $280,000 price point you are selling to someone who has four other options on the same street.

Walking a property as a contractor, he’s also reading the structure. Big cracks in walls, significant visible foundation settlement — those move a property out of consideration before he gets to the spreadsheet.

Deal-Killers: Flood Zones, Sinkholes, and Settlement

Brown buys Flood Zone X and nothing else. Not AE, not any part of the 100-year floodplain, regardless of how the house performed in actual storms.

The reason is price point, and he’s explicit about it. At the ARVs he works in, an extra $200 to $300 a month for flood insurance makes or breaks the deal for his buyer. On a million-dollar house, nobody notices $300 or $400 a month — that buyer isn’t even seeing it. At $280,000, that premium is a material change to the monthly payment, and it sends the buyer to a different listing.

Sellability is the second problem, and it’s independent of the math. Brown has bought and sold plenty of homes in AE zones that stayed completely dry through the worst flooding the Tampa Bay area has seen in recent hurricanes — houses that will likely never flood in their lifetime. They still require flood insurance, and they still carry the stigma. The stigma alone narrows the buyer pool.

There’s a third angle if you ever plan to hold. That same $200 a month runs straight through your DSCR calculation. On a house renting for $2,800, Brown says it can be the difference between refinancing out and being stuck.

Two more hard nos:

• Sinkhole-remediated homes. Not because the remediation is necessarily bad work — because they are not easy to sell, no matter how they look.
• Major visible settlement. Big wall cracks, significant foundation movement. He strays away from these entirely.

I never cared what the wholesaler makes. If the deal worked for me, that’s all I care about. I’m only scheduled to make $40,000 on this deal, but I know I’m going to make $40,000 on this deal. So whatever you make, make.

Winning MLS Deals Without Being One More VA Text

The MLS is still a productive channel, but only at two ends of the timeline. Brown targets listings posted within the last couple of hours, or listings that have been sitting 60 to 70 days. The middle is dead space.

The problem with the fresh end is obvious to anyone who’s tried it. Virtual assistants scour the feed hourly with saved parameters. The moment a hot listing goes live, the listing agent gets bombarded — boom, boom, boom, within minutes. Your offer arrives as message forty in a stack of identical messages, most of them from people who cannot actually close.

Brown’s differentiation is the delivery and the terms together. He texts the listing agent directly from his personal phone and leads with who he is:

• He’s the owner of the company — not a VA, not a wholesaler, not a PM
• He’ll sign a buyer-broker agreement
• He’ll sign a contract that is not assignable
• Zero-day inspection period
• $5,000 earnest money
• Wire goes out within the hour if they reach agreement

The non-assignable clause is the part that separates him from the noise, and he can offer it because he isn’t wholesaling. If he wants the property, he’s flipping it or refinancing into a hold. That means every term he offers is a term he can actually perform on.

As he puts it, the agent knows they’re talking to the guy who makes the deal and signs the checks. For a listing agent who has spent the morning deleting wholesale texts, that’s a short conversation worth having.

Where Flip Profit Actually Comes From

Brown’s working number is $40,000 to $60,000 of spread on a flip with a $280,000 ARV. He hits it consistently enough that he treats it as the underwriting input, not the hoped-for outcome.

Because the number is stable, the assignment fee on the front end stops mattering. He paid a wholesaler $60,000 on a $130,000 acquisition — a property the wholesaler had locked up at $70,000 — and it never bothered him. He’d negotiated from $150,000 down to $130,000 and the deal still worked at his number. His position: he doesn’t care if the wholesaler bought it for a dollar. If the deal clears his spread, the deal clears.

He says this directly to wholesalers who want to double-close to hide a fee. “I’m only scheduled to make $40,000 on this deal, but I know I’m going to make $40,000 on this deal. So whatever you make, make.”

The practical payoff is that Brown runs no acquisitions department. He doesn’t dial until he’s blue in the face or sit at kitchen tables hunting a golden goose. Deals arrive because he built a pipeline — title companies, wholesalers, pocket listings from other flippers who passed — and he rinses the same repetitive process.

Inbound volume in Tampa has gone up noticeably. Brown describes something like a wholesaler migration into the market, which produces a side effect worth knowing: inexperienced wholesalers price deals wrong. He gets properties sent at $150,000 that should have been sent at $190,000. He locks those up.

Probate and Multi-Heir Deals: Where to Stop and Hand Off

Florida probate deals carry real margin, and Brown’s rule is to work them only as far as his own competence goes, then hand off.

What he’ll handle himself: a straightforward situation with three to five heirs where he can make contact with one of them. He buys out that heir’s individual interest, then enlists them — paid, or just because they’re willing — to help locate the remaining heirs. Chipping away one interest at a time.

What he hands to a curative title specialist: anything with deceased relatives in the chain, heirs who don’t want to sell, specific affidavits that need filing, or partition exposure. His framing is that there is always a path to the finish line, but the knowledge required to find it is a specialty. The moment he’s getting real pushback or doesn’t know what he’s doing, it goes to someone who does.

Timeline expectation: six to twelve months. Longer if litigation enters the picture. Underwrite holding and carry accordingly, because a deal that takes a year to close is a different deal than one that closes in thirty days — even at the same price.

These are what Brown calls path-of-most-resistance deals, and they’re among the most profitable he sees. The margin exists precisely because of the loose ends. A traditional agent doesn’t want to coordinate five heirs who aren’t speaking. That coordination is the product.

Ground-Up and Capital Reserves Before You Switch Lanes

Ground-up construction is more controlled than rehab on the build side — fix and flip is full of unforeseen conditions, especially on physically distressed property — but the front end is where flippers get caught.

Land acquisition is the capital problem. Lenders want a permitted set of drawings. Raw, unentitled land with nothing prepared is hard to finance, which means a large lump sum out of pocket just to secure the dirt. Once you’re permitted and moving, a construction vehicle can cover most or all of the land cost plus the build. Getting to that point is on you.

Entitlement is the second problem, and it’s hyper-local. Utilities, infrastructure, parking, height requirements, and regulations differ from one part of a city to another, let alone one jurisdiction to the next. Brown notes the City of Tampa is not easy to work with and routinely adds requirements you didn’t plan for. This is why builders stay in one geography — learn the rules once and rinse and repeat instead of eating the learning curve again.

Two accelerators he says are not gatekept so much as unknown:

1. Move plan review and inspections to a private provider. Take as much out of the city’s hands as the jurisdiction allows. Still do the city’s required pre-construction inspections, but private provision is the biggest lever on speed to market.
2. Secure a reliable subcontractor pool. Mismanaged scheduling eats you on holding costs, opportunity costs, and permit expiration.

On capital: don’t venture into fix and flip without $50,000 to $60,000 that could catch fire and disappear without leaving you distressed. Brown is blunt that funding a first flip with credit cards is among the worst financial advice going. If something goes wrong, you owe $50,000 to a creditor who is coming to get it while you’re still trying to make your mortgage.

One more lesson, from his own scaling from two flips to 22 in a year: he lost the position not from overextending on deals but from not delegating the monotonous back office — turning on utilities, paying interest, paying credit card bills. When the operator stops, everything stops. Hire for that before you need to.

Frequently asked questions

What ARV cap should I use on a flip to keep the buyer pool wide?

Frank Brown caps ARV at roughly $400,000 in the Tampa market so the finished house qualifies for all loan vehicles, which keeps the widest possible pool of retail buyers in play. The cap is market-specific — the principle is to stay below the threshold where loan products start dropping off in your area.

That ceiling also drives the rest of his criteria: under 1,500 square feet, 3/2 or 2/2, single story. Those specs are what it takes to land under $400K in a market with persistent affordable-housing demand.

Is it ever worth flipping a house in a flood zone?

At a sub-$400,000 ARV, Brown says no — he buys Flood Zone X only. An extra $200 to $300 a month in flood insurance materially changes the payment for a buyer at that price point, and the flood-zone stigma narrows the buyer pool even on homes that stayed dry through recent hurricanes.

His own framing is that the price point is what makes it a deal-killer. On a million-dollar house, that same premium disappears into the payment and the buyer doesn’t react to it. If you plan to hold and refinance, add the DSCR hit: $200 a month against $2,800 in rent can be the difference on a refi.

How do I get a listing agent to take my offer seriously when VAs are texting them all day?

Identify yourself as the decision-maker and attach terms a wholesaler cannot offer. Brown texts listing agents directly from his personal phone, states that he’s the company owner and not a VA or wholesaler, and offers to sign a buyer-broker agreement and a non-assignable contract.

He pairs that with zero-day inspection, $5,000 earnest money, and a wire going out within the hour of agreement. The non-assignable clause is the credibility signal — he can offer it because he’s keeping or flipping the property himself.

Should I care how big the wholesaler’s assignment fee is?

No, if your own number still works. Brown paid a $60,000 assignment fee on a $130,000 acquisition price and didn’t care, because his expected $40,000 to $60,000 spread was intact.

Treating the wholesaler as a free acquisitions department rather than a competitor is what lets him do volume without running a marketing operation. The fee is the wholesaler’s business; the spread is yours.

How much cash do I really need before my first flip?

Brown puts the number at $50,000 to $60,000 — and specifies it should be money that could catch fire and go away without leaving you financially distressed. That’s not the deal budget; that’s the cushion.

He’s specifically against funding a first flip with credit cards or money that’s currently paying your bills. If the project goes sideways, you owe the full amount to a creditor who will come collect while you’re still covering your own mortgage.

The bottom line

Write your buy box down as hard filters before you look at another deal — ARV ceiling, square footage, layout, flood zone, structural red flags — and then actually refuse the properties that fail it. The investors who survive a tough market are the ones whose screen does the saying-no for them.
