Why a buried oil tank stops a Farmingdale sale
The median house in Farmingdale sold for $759,611 and took about 25 days to go under contract, then another 45 to 60 days waiting on the buyer's mortgage. That is 70 to 85 days in total, for a house that was ready to show on day one. That is the ordinary path, and an oil tank in the ground tends to interrupt it.
The problem is not really the steel. It is liability. A buyer's attorney sees an unremoved oil tank and thinks about what happens if it leaked, because whoever owns the property afterward inherits that question. Lenders are no keener on an unresolved environmental item sitting against their collateral. So the contract stalls while everyone works out who is paying to find out, and a stalled Farmingdale contract has a way of never restarting.

What we take on with a buried oil tank, and who we call
The most useful thing we can give somebody with a buried oil tank is proportion. Owners get quoted alarming figures, buyers imagine worse, and nobody in the transaction actually knows what is under the lawn.
We have bought and remediated enough of these to have a view. The age of the house, where the fill pipe and vent sat, how the conversion to gas was handled, what similar Farmingdale properties have turned up when the excavator arrived. Tell us what you know about the oil tank, even if that is almost nothing, and we will tell you plainly what usually happens next.
Why local knowledge changes the number
The median is up 5.5% year over year as of 2026-10. 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. A $759,611 median puts Farmingdale in the band where buyers are stretching to afford the house and have nothing left for the roof. That is precisely the buyer who walks away from a property needing work, and it is why condition matters more here than the price alone suggests. The median house here goes under contract in about 25 days, which is quick for Long Island. It is also a figure that only applies to property in showable condition.
Farmingdale is roughly 8,466 people in Nassau County, ZIP 11735, and the housing stock is mostly cape cod, colonial, ranch. Around Main Street and Conklin Street, most of it is old enough that the mechanicals are on their second or third life. The Farmingdale stop pulls buyers who commute, which supports the good houses and does very little for the ones that need a roof. We have been buying across Nassau County for 15+ years. We know what the Farmingdale Union Free School District does to a resale price, which blocks still have oil tanks in the ground, and what a house like yours is actually worth here.
Save your money on the oil tank test
The order people usually reach for is: remove the oil tank, then sell. It is the natural instinct and it is frequently the costly one.
Once the excavator is on site and the tank is out, whatever the ground shows becomes yours to deal with, mid-sale, with a buyer waiting. Sellers who go that route sometimes watch the job double while they are standing in the yard. Selling with the oil tank in place moves that risk to us, which is most of the reason to do it this way.
The difference between an oil tank and an oil tank that leaked
The worst case with a buried oil tank is that product got out and traveled, and then you are dealing with soil rather than steel. It is a real scenario and it is why buyers get nervous.
We price for it. Our offers on tank houses assume the oil tank is a live question rather than a formality, which is why our number tends to hold once we have given it. If the excavation turns out clean, that is our upside. We would rather carry that risk than hand it back to you halfway through a closing.
What the two paths cost in Farmingdale
These are the two routes open to you with a house with a buried oil tank, priced against what Farmingdale houses actually sell for.
Work it against Farmingdale's own numbers. The median sale here is $759,611. A 5% commission on that is $37,981, and seller closing costs of about 2% add roughly $15,192. Those are costs we can cover on our side. That is $53,173 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 Farmingdale the median house takes about 25 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 70 to 85 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 | $759,611 (Farmingdale median) | Our written offer |
| Commission | −$37,981 | None |
| Seller closing costs | −$15,192 | We can cover them |
| Repairs before listing | Out of pocket | None |
| Cleanout | Yours | Ours |
| Showings | Until it sells | One visit |
| Listed to signed contract | 25 days (Farmingdale 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 | 70 to 85 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 | $706,438 | The number we put in writing |
The listing column assumes a 5% commission and seller closing costs of about 2%. Both vary. We have not subtracted repairs or the cost of carrying the house while it sits, because those depend on the property. A house in good condition listed with a good agent can absolutely beat a cash offer, and we will say so if that is your situation.
No lender to satisfy, and no oil tank condition to clear
On a financed sale the seller is usually the one asked to pay for the oil tank work up front, on a house they are leaving, for a buyer who can still walk away afterward. That is an impossible position, and plenty of people accept it anyway because they believe there is no alternative.
There is. We buy with the oil tank in place, at our cost and our risk, and the money stays in your pocket instead of going into the yard.

Oil tank disclosure, paperwork, and who to ask
If there is paperwork anywhere, it helps. An old permit, a receipt from whoever did the conversion to gas, a note from a prior closing, anything a previous owner left in a drawer. Your town's building department may hold records of work done at the address, and it costs nothing to ask them.
If there is nothing at all, that is the usual case with a buried oil tank and it does not slow us down. We have bought plenty of Nassau County houses where the only evidence of the tank was a capped fill pipe beside the side door.
Common questions
Do I have to remove the oil tank before you buy a Farmingdale house?
No. We buy with the oil tank in the ground. Removal is our cost and our project after closing, not something you arrange first.
How do I know whether there is still an oil tank buried in my yard?
The usual signs are a capped fill pipe or vent on the side of the house, a boiler that was converted to gas, or copper lines running to nowhere in the basement. A tank company can sweep the yard and settle it. Your town's building department may also hold records for the address.
What if the oil tank leaked?
A leak widens the work, and there may be reporting considerations in New York, which is a question for your attorney and an environmental contractor. From our side we still buy. Tell us early so the offer is right the first time.
A buyer walked away over the oil tank. Does that hurt my chances with you?
No. Most Farmingdale owners who call us about a buried oil tank have already had a contract die on it. That is the usual route here, not a mark against the property.
Does the oil tank change what you can pay?
It affects the number the way any real cost does, because the removal and whatever the ground needs have to be paid for by somebody. What it does not do is end the conversation.
