There's a flyer in the mailbox, maybe a postcard. "We buy houses. Any condition. Cash in 7 days." And honestly, if you're sitting on a property that needs work, that sounds pretty good.
Here's the thing though. That offer is priced for the person who doesn't know what else to ask.
I've seen this enough times now that I want to write it down clearly. The gap between a wholesale cash buyer's number and what a developer will actually pay is not a rounding error. On a lot-value property along the Shore — Stone Harbor, Avalon, Sea Isle, Cape May County in general — that gap is regularly $150,000 to $300,000. Sometimes more.
That is not a pitch. That is a structural problem worth understanding.
How the "We Buy Houses" Number Gets Made
Wholesale buyers — the ones behind those postcards — operate on a formula. It's called the Maximum Allowable Offer, or MAO. The basic version looks like this: After Repair Value × 70% minus estimated repair costs. That's it. That's the ceiling they can pay and still make money on a flip or assignment.
On a Shore property trading at $800,000 in rough shape, that formula spits out somewhere in the low-to-mid $500,000s. Maybe $520,000. Maybe $540,000 depending on who's running the numbers.
A developer looking at the same property is running a completely different model. They're not thinking about the house. They're thinking about the land. Zoning envelope. Lot dimensions. What can actually be built. What a new build on that footprint will sell for when it's done.
Those are different math problems with very different outputs.
(I had to look up some of the MAO formula variants because they've drifted over the years — some wholesale buyers have pushed their multiplier down to 65% in markets where resale competition is thinner, which makes the gap even wider.)
The cottage on 50th Street in Sea Isle that sold recently — I'm not going to give you the exact address — was listed off-market. A postcard buyer came in at $490,000. The developer offer that actually closed was $720,000. Same property. Same week. Thirty days between contact and closing on both.
What Developers Are Actually Buying
When Redfern looks at a property, we're underwriting the land. Full stop.
The house — even if it's livable, even if someone's been renting it for decades — is largely irrelevant to our number. What matters is: lot width, lot depth, zoning district, FEMA base flood elevation, setbacks, whether there's an existing structure we'd have to demo or whether it's already cleared.
Owners in the 60x110 lot range tend to ask why we value their property so differently than what Zillow shows. The answer is that Zillow is estimating replacement cost on a residential asset. We're underwriting a development site.
Those are not the same thing.
If your property is in a district where new construction is selling at $2.2M to $2.8M, and your lot can support that program, the land value isn't $400,000. It's significantly more than that. The lot value calculation for Avalon and Stone Harbor look different from each other, and different again from Sea Isle — but the underlying logic is the same.
The wholesale buyer never runs that model. They don't need to. They're not building anything.
Here's the Uncomfortable Part
I want to be honest about when a cash buyer's offer might actually make sense.
If you have a property with significant deferred maintenance, environmental issues, title complications, or you genuinely need to close in under two weeks for personal reasons — the speed and certainty of a wholesale offer has real value. I'm not going to pretend it doesn't.
Developer deals, including ours, involve due diligence periods. Sometimes longer than sellers want. There's permitting research, title review, occasionally soil testing. The process is cleaner than a traditional listing, but it's not seven days.
So if the premium is $200,000 and the timeline matters more than the money, that's a real tradeoff and only you can make it.
What I'd push back on is the seller who doesn't know the tradeoff exists. That question comes up a lot — "I didn't know I had options." That's the gap I'm trying to close.
The hidden cost curve on Shore homes also factors in here — a lot of sellers in older properties have been carrying deferred maintenance costs for years and assume that story hurts them everywhere. With a developer, it mostly doesn't. We're demolishing the structure anyway.
The Variables That Move the Number
Not every Shore property is a development candidate. Some lots are too narrow. Some are in flood zones that make the economics impossible. Some are in municipalities with zoning restrictions that cap what can actually be built.
When Redfern looks at a property, these are the variables that move our number up or down — not the condition of the kitchen or whether the deck needs to be replaced.
- Lot dimensions relative to zoning minimums
- Current base flood elevation and FEMA map revision risk
- Setback requirements and what buildable footprint they leave
- Comparable new construction sale prices in the past 12-18 months
- Proximity to water (bay vs. ocean block vs. interior)
- Municipal permitting history and typical approval timelines
The relationship between building codes and property value shifts this calculus more than most sellers realize. A lot that looks identical to the one next door can price $75,000 differently based on FEMA elevation requirements alone.
Wholesale buyers don't model any of this at that level of detail. They're pricing in bulk, applying a formula, and moving on.
One-sentence paragraph:
The formula doesn't know what your lot is worth. You should.

If you're fielding a cash offer right now, or wondering what a developer would actually pay for your property — you deserve a real number to compare it against.
What would you do differently if you knew the gap was $200,000?
