Unpermitted work is ordinary in older Hempstead houses
You may not know which parts are the problem, and that is common. Owners who bought years ago inherited whatever the previous owner built and had no reason to go looking.
A certificate of occupancy describes the house the town believes it approved. If the basement, the deck or the extension is not in that description, the work was very likely done without a permit. An expeditor or an attorney can pull the file and tell you where the gaps actually are.
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 Hempstead specifically
Hempstead is roughly 59,169 people in Nassau County, ZIP 11550, and the housing stock is mostly colonial, cape cod, tudor. Around Fulton Avenue and Main Street, most of it is old enough that the mechanicals are on their second or third life. The Hempstead stop pulls buyers who commute, which supports the good houses and does very little for the ones that need a roof. We know which of these streets take water, where the older systems fail first, and what the Hempstead Union Free School District does to a resale price.
The median is up 6.02% year over year as of 2026-05. A firming market gives you a little room for error on price, which is worth more than it sounds when the house is not in showable condition. At a $660,000 median, Hempstead 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. Houses here take a median of 57 days to go from listed to under contract, and that clock only starts once the property is ready to show.
Appraisals, unpermitted square footage and the certificate of occupancy
The awkward part is how late it surfaces. Everything feels fine until a search comes back and the deck, the basement or the extra bathroom is not on file anywhere and no permit was ever pulled.
By then there is a signed contract, a mortgage commitment with conditions attached, and a buyer who has started packing. Renegotiation follows, then often a collapse, and a Hempstead house goes back on the market with more days on it and a story attached.
Why legalizing unpermitted work takes longer than anyone expects
The construction itself can be the smallest part. Drawings have to be produced, an application filed, fees paid, and inspectors given access to things that are now behind finished walls, which sometimes means opening them up again.
Then there are the outcomes nobody plans for: a structure standing where nothing is allowed to stand, or a conversion the zoning will not allow at all. Legalizing unpermitted work can end in a variance application, and that is a timeline of its own entirely.
What the two paths cost in Hempstead
These are the two routes open to you with a house with unpermitted work, priced against what Hempstead houses actually sell for.
Work it against Hempstead'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 Hempstead the median house takes about 57 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 102 to 117 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 (Hempstead 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 | 57 days (Hempstead 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 | 102 to 117 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 |
For the listing side we have used a 5% commission and about 2% in seller closing costs; your real figures may differ. Repairs and carrying costs are left out because they depend on the house. If yours is in good shape, a good agent may well get you more than we would, and we will tell you if so.
Legalizing the unpermitted work first, or selling as-is
The comparison worth making is not our offer against an asking price. It is money in hand on a date you choose, set against a listed number minus commission, minus whatever the permit process costs, minus the concessions a buyer asks for once the file comes back, and minus several months of carrying a Hempstead house.
We will lay ours out in writing so it can be compared honestly. If the listing wins on that arithmetic, take the listing.
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 Hempstead 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 Hempstead the stock is largely colonial and cape cod, and on houses that age the mechanicals are usually the expensive part rather than the cosmetics.
- How long we will hold it. The median Hempstead house goes under contract in about 57 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.
What to do next
Nothing has to be legalized, opened up, drawn or approved before we buy. The unpermitted work stays exactly as it is through the closing, and the file becomes ours.
That is not a concession, it is simply the work we do. We take on the file, commission the drawings, meet the inspectors on site and pay for the corrective work when one of them asks for it. What would be a year of your life, spent on a house you have already decided to leave, is a line in our budget.
Common questions
Will unpermitted work stop a buyer getting a mortgage on a Hempstead 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 Hempstead 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?
It is extremely common and it does not affect our offer. What you are personally exposed to is an attorney question, but unpermitted work done by a previous owner is not a reason we walk away.
Will the town find the unpermitted work when I sell my Hempstead house?
A buyer's attorney will usually order a municipal search, which is where open permits and missing sign-offs surface. Selling to us does not require that search to come back clean.
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 Hempstead 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.
