What usually turns out to be unpermitted
The list barely changes from house to house. Finished basements, rear decks, dormers, a garage turned into a bedroom, a sunroom off the kitchen, a second kitchen put in for a relative who moved in years ago.
Most of it was built competently by people who knew what they were doing. It simply never went through the building department, and the work stays unpermitted no matter how well it was built or how long ago it happened.
What we bring to unpermitted work, beyond the money
Most owners get here after one call to the building department that raised more questions than it answered. What we can offer first is somebody who has been through this repeatedly telling you plainly what your options are.
If selling suits you, we buy with the unpermitted work in place. If the addition could be legalized without much trouble and the house would net more legalized and listed, we will say so and give you the name of an expeditor. Neither conversation costs you anything.
What this looks like in Freeport specifically
Freeport is roughly 43,713 people in Nassau County, ZIP 11520, and the housing stock is mostly cape cod, ranch, colonial. Around Freeport Nautical Mile and Freeport LIRR station, most of it is old enough that the mechanicals are on their second or third life. The Freeport stop pulls buyers who commute, which supports the good houses and does very little for the ones that need a roof. We have bought enough here to know which streets take water, which blocks still have oil tanks in the ground, and what the Freeport Public Schools does to a resale price.
The Freeport median has barely moved year over year as of 2026-05, at 0.76%. Flat is the hardest market to price a fixer into, because there is no upward drift to cover a mistake and no urgency pushing buyers to overlook a problem. At a $660,000 median, Freeport is a market where buyers expect to do some work. That helps a seller with a dated house and hurts one with a genuinely broken one, because the pool that will take on a project is not the same pool that will take on a gut. The median house goes under contract in about 47 days, which is not slow - but it describes houses that were already showable on day one.
Appraisals, unpermitted square footage and the certificate of occupancy
Two separate parties care, which is what makes this harder than people expect. The lender wants the value it is lending against to be real and legal. The title company wants the buyer to take the property without open items attached to it.
An open permit or a missing sign-off can show up as an exception on a title report, and work done off the books has a way of producing both at once. Satisfying one of them is manageable. Satisfying both on a contract timeline is where sellers come unstuck.
Why legalizing unpermitted work takes longer than anyone expects
Ask an attorney or an expeditor before you assume anything, in either direction. We have seen owners spend months chasing approvals they were never going to get, and we have seen others avoid selling for years over something that would have been permitted in a season.
The only way to know which one you have is to put the file in front of somebody who works with that department regularly. We are glad to tell you who we would call in Freeport, and there is nothing owed to us for it.
What the two paths cost in Freeport
These are the two routes open to you with a house with unpermitted work, priced against what Freeport houses actually sell for.
Work it against Freeport's own numbers. The median sale here is $660,000. A 5% commission on that is $33,000, and seller closing costs of about 2% add roughly $13,200. Those are costs we can cover on our side. That is $46,200 gone before anyone counts the repairs it took to get the house listable.
There are two waits in a listed sale and people usually only count the first. In Freeport the median house takes about 47 days to go from listed to a signed contract. Then it waits again, typically 45 to 60 days, while the buyer's lender orders an appraisal and underwrites the loan. Call it 92 to 107 days from sign to keys, assuming nothing goes wrong.
The part worth understanding is what a signed contract actually guarantees, which is less than most sellers assume. A retail buyer with a mortgage contingency can walk away right up to the end. If they do not qualify, if the appraisal comes in under the price, if they change their mind and let the financing lapse. A share of deals die exactly there, after months of waiting, and the house goes back on the market with time on it. We are not borrowing anything, so there is no lender to satisfy, no appraisal to come in low and no contingency to exercise.
| Listing with an agent | Selling to us | |
|---|---|---|
| Sale price | $660,000 (Freeport median) | Our written offer |
| Commission | −$33,000 | None |
| Seller closing costs | −$13,200 | We can cover them |
| Repairs before listing | Out of pocket | None |
| Cleanout | Yours | Ours |
| Showings | Until it sells | One visit |
| Listed to signed contract | 47 days (Freeport median, once listable) | 24 hours to a written offer |
| Contract to closing | 45 to 60 days (waiting on the buyer's lender) | A date you choose |
| Total wait | 92 to 107 days if nothing falls through | Yours to set |
| Can the buyer walk? | Yes (mortgage contingency runs to the end) | No financing to fall through |
| Before repairs and carrying | $613,800 | The number we put in writing |
Assumptions: 5% commission and about 2% seller closing costs on the listing side, and both move from deal to deal. Repairs and the cost of holding the house are not deducted, since they vary by property. A well-kept house with a good agent can come out ahead of a cash sale, and if that describes yours we will say it.
Which route nets more when the work was never permitted
Sometimes legalizing first is genuinely the better move, and we will tell you when we think so. A deck that needs a permit and an inspection is a different proposition than a garage conversion the zoning may never allow.
The calculation turns on what has to be spent before anything is recovered. Permit costs, drawings, the corrective work an inspector asks for, and the months the house carries while all of it happens. A cash sale frequently wins on the net rather than on the headline number.
How we arrive at a number on a house with unpermitted work
On a house with unpermitted work we start from the end: what it sells for once the work is done. From that we take away the cost of the work and a margin for the chance that we have misjudged either one. That is the whole method. Nothing is hidden in it.
- What it is worth repaired. Not the Freeport median of $660,000 on its own, but what houses like yours on your street actually closed at recently.
- What the work costs. Roof, boiler, electric, the kitchen and bath. In Freeport the stock is largely cape cod and ranch, and on houses that age the mechanicals are usually the expensive part rather than the cosmetics.
- How long we will hold it. The median Freeport house goes under contract in about 47 days once it is showable, then waits 45 to 60 days more on the buyer's lender. Ours has to get to showable first, and we carry taxes and insurance across the whole of it.
- What we are wrong about. Walls and floors hide things until they come up. We price for that uncertainty, and it accounts for much of the distance between a cash offer and a retail price.
How we can pay this and still make it work
Most cash buyers skip this part. We do not. We run millions of dollars of construction a year, so we buy materials at contractor prices and keep our crews busy all year. The same renovation costs us roughly half of what you would be quoted as a homeowner.
That difference is how we make money. It is also why renovating before you sell seldom comes out ahead: you would pay retail for the roof and the boiler and then hope a buyer pays you back for them. Most of the time they do not. Our margin comes from building for less, not from buying from you for less.
If our number does not work for you, tell us. We would much rather hear it than push. We will go through your situation and give you a straight view of your options, including the ones that leave us out. A lot of people do better listing with an agent, and if you are one of them we will tell you now rather than have you find out later.
No permit has to be pulled before you sell
The next step is short. Tell us what was built and roughly when, send whatever the town has sent you, we come out once, and you get a written number within a day.
No permits, no drawings, no cleanout, and no sign on the lawn in Freeport. If what we see suggests the work could be legalized easily enough that you would net more that way, we will tell you so and give you the name of the expeditor we would use.
Common questions
Will unpermitted work stop a buyer getting a mortgage on a Freeport house?
It often does. A lender wants the certificate of occupancy to match what is physically there, and unpermitted work means it does not. The appraiser flags the discrepancy, the underwriter asks for the permit, and the buyer is suddenly waiting on a town approval nobody can put a date on. That is the mechanism behind most failed sales on houses with unpermitted work. We are not borrowing, so there is no appraiser and no underwriter to satisfy.
Do I have to pull permits before selling my Freeport house?
No. Pulling permits after the fact is slow and expensive, and it is work we are already set up to do. Spending your own money and months on it before you have an offer in hand rarely makes sense.
The previous owner did the unpermitted work. Does that change anything?
Not for us, and not for the town either, because the file follows the property rather than the person who built the addition. It is one of the most common versions of this we see.
Will the town find the unpermitted work when I sell my Freeport house?
What the town knows and when is not something anyone should guess at. Your attorney can tell you what a sale in your situation actually triggers. From our side, nothing you disclose changes our offer.
There is already a violation for the unpermitted work. Can you still buy?
Yes. An open violation on unpermitted work is a file we take on at closing along with the house. It affects the number the way any real cost does, not the willingness.
How much does unpermitted work take off the price of a Freeport house?
Enough to cover what it realistically costs to put right, and no more than that. We will show you how we arrived at the figure, and we do not move it afterward.
