Where our experience with Uniondale back taxes helps
Owing back taxes on a house is one of those things people carry privately, and almost everybody who calls us about it expects to be judged for it. Nobody here is going to do that. The most common misunderstanding is that the arrears have to be cleared before a sale can happen, and they do not. They are settled out of the purchase price at closing.
We buy Uniondale houses with years of arrears against them. The first thing we will help you do is get the current figure from the county, because interest moves it and an old bill understates what is owed. From there the arithmetic is straightforward, and we will show you all of it rather than handing you a number and asking you to trust it.
Back taxes get paid from the sale, not from your savings
Nobody has to pay off back taxes out of pocket to make an Uniondale sale possible. The proceeds do that job.
What we would ask you to do instead is get the payoff figure in writing from the county, so the number on the closing statement surprises nobody. That one piece of paper removes most of the uncertainty people carry into these conversations, and it is free to request.
Why local knowledge changes the number
The median has slipped 1.95% year over year as of 2026-10. It is a small move, but a softening market punishes the houses that need work first - buyers with choices do not choose the project. At a $684,649 median, Uniondale 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 50 days to go from listed to under contract, and that clock only starts once the property is ready to show.
Uniondale is roughly 32,473 people in Nassau County, ZIP 11553, and the housing stock is mostly cape cod, colonial, ranch. Around Hempstead Turnpike and the Nassau Coliseum, most of it is old enough that the mechanicals are on their second or third life. We have been buying across Nassau County for 15+ years. We know what the Uniondale 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.
Back taxes in Nassau County, and where they lead
Delinquent property taxes in Nassau County accrue interest and eventually lead to enforcement, so the current figure is worth getting from the county directly rather than working from an old bill.
What matters for you is that back taxes accrue interest and eventually lead to enforcement, so the cost of waiting is real and it compounds. Get the current figure from the county rather than working from an old bill, and ask an attorney where in that process your house actually sits. If you do not have one, we can point you to somebody who does this work regularly.
Back taxes on an Uniondale house that have gone to a lien sale
The point at which back taxes stop being a bill and start being somebody else's lien is the point at which speed begins to matter.
Establishing which stage you are at is quick. The county can give you the current figure in writing, and an attorney can tell you what has already been filed against an Uniondale property. Once you know, tell us, and we will be straight with you about whether a sale still works from where you are standing.
What the two paths cost in Uniondale
These are the two routes open to you with a house with back taxes, priced against what Uniondale houses actually sell for.
Work it against Uniondale's own numbers. The median sale here is $684,649. A 5% commission on that is $34,232, and seller closing costs of about 2% add roughly $13,693. Those are costs we can cover on our side. That is $47,925 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 Uniondale the median house takes about 50 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 95 to 110 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 | $684,649 (Uniondale median) | Our written offer |
| Commission | −$34,232 | None |
| Seller closing costs | −$13,693 | We can cover them |
| Repairs before listing | Out of pocket | None |
| Cleanout | Yours | Ours |
| Showings | Until it sells | One visit |
| Listed to signed contract | 50 days (Uniondale 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 | 95 to 110 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 | $636,724 | 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.
Protecting the equity in an Uniondale house from back taxes
Back taxes are one of the few problems in a house that grow on their own. Nothing has to happen for the number to get larger. Interest and penalties do it while the mail sits unopened on the counter.
Every dollar added comes out of the equity you would otherwise walk away with, not out of anybody else's side of the ledger. That tends to be the more persuasive argument for dealing with it sooner, because the enforcement argument is easy to postpone and this one is not.

If the back taxes leave nothing for you
Not every owner with back taxes owed should sell. If you want to keep the house and there is a realistic path to doing that, we would rather help you find it than walk you through a process that ends somewhere you did not want to be.
We can point you to a housing counselor, to an attorney who handles tax enforcement, and to a CPA if there is a tax question buried in this that deserves a professional answer. Ask us. The worst outcome of the call is that you leave it knowing more than you did.
Common questions
How do I find out what back taxes I owe on my Uniondale house?
The county is the only reliable source for the current back taxes figure on an Uniondale property. Request it in writing, and if you are not sure which office to ask, tell us and we will point you at the right one.
Can you buy an Uniondale house with years of back taxes on it?
Yes, provided the total owed still leaves a workable number. We will show you the arithmetic rather than just quoting you a figure and hoping you accept it.
Do I have to pay the back taxes off before closing?
Not in the ordinary case. The arrears come off the top of the proceeds at closing. Please talk to us and to an attorney before you spend savings on the assumption that you have to clear them first.
What happens to the back taxes if I do nothing?
They accrue interest and the county continues through its enforcement process. Exactly where that leads and how quickly is a question for an attorney, and it is worth asking sooner than feels comfortable.
Will I have anything left after the back taxes are paid at closing?
Often yes, and sometimes no. Get the written figures for the back taxes and the mortgage payoff first, because everything else is guesswork until those two numbers exist.
