Local cash buyer or iBuyer: what the algorithm cannot see

The big instant-offer platforms are real companies with real offers — for the right house. Here is where their model works, where it quietly does not, and why coastal North Carolina is mostly the second kind.

Because I hold a broker’s license and buy houses for cash, I get asked constantly which one is the trick. Neither is. They are different tools, and the only trick is using the wrong one. These guides are the comparisons I walk sellers through at the kitchen table.— Matthew Kane, founder

Two very different machines

An iBuyer prices thousands of houses with a model, buys the predictable ones, charges a service fee, and resells at scale. A local cash buyer walks your actual house and prices its actual problems. Neither is a scam; they are built for different inventory. The question is which machine your house fits.

Where the model shines

Uniform houses in uniform neighborhoods

Newer tract homes with standard floor plans and clean records are exactly what pricing models are good at. If you own one and an iBuyer serves your zip code, their offer can be strong and their process is genuinely convenient. I will say that plainly because it is true.

Where the model struggles

Character, condition, and coast

A 1948 house near the river, a home with Florence history in the crawlspace, septic on a county lot, an addition without paperwork, wind-and-hail insurance quirks — the model either declines these outright or protects itself with a wide price band and a heavy post-inspection adjustment. Much of the Cape Fear housing stock lives on this list. It is also worth checking whether the major platforms actively buy in Wilmington at all before counting on one; coverage here has been thin and changeable.

The fee question

Service fees versus discounts, honestly compared

iBuyers typically charge a service fee in the range of listing commissions, then adjust for repairs after their inspection. Local buyers build everything into one number up front. Neither structure is dishonest, but they hide the cost in different places: read the iBuyer’s final adjusted net, not the headline, and hold our number to the same standard — the math is in our offer-calculation guide.

The certainty question

Re-trades and walk-aways

The pattern that burns sellers is the post-inspection price drop days before closing, when moving trucks are booked and leverage is gone. Ask any buyer — platform or local — two questions: when is your price final, and what can still change it? Our answer: the written number after we see the house is the number, and we have closed on houses other buyers re-traded. Hold everyone, including us, to that.
