Buying on Long Island
Buying a house on Long Island
What the process actually involves here, and what 84 closed sales say about how fast you will need to move.
Most buying advice is written for the country as a whole. Long Island is not the country as a whole. It is an attorney state, the housing stock is old, the taxes are the second mortgage nobody budgets for, and the good houses are gone in under three weeks.
What follows is the sequence John Tiburzi takes buyers through, with the figures from his own 84 closed sales attached where they say something useful. Where a number comes from that record, the count it is drawn from is stated, so you can see how much weight it carries.

01
Sort the money before you look at a single house
A pre-approval is not a rate quote and it is not a pre-qualification. It is a lender saying they have looked at your income, your credit and your assets, and they will lend. Sellers here treat an offer without one as a conversation rather than an offer.
Work out the payment including taxes, not the payment the mortgage calculator shows. Across 82 of these sales the annual tax bill ran from $2,690 to $19,848, with a middle figure of $10,616. At the top of that range the taxes alone add well over a thousand dollars a month to what you owe, and two houses at the same price can be a long way apart on what it costs to keep them.

02
Understand what the market does to buyers here
Of 84 sales with a recorded asking price, 78 closed at or above what the seller was asking. That is 93 percent. Going in under asking as an opening position is a strategy that mostly buys somebody else the house.
Speed matters just as much. The middle sale went to contract in 18 days, and 33 of 83 were gone inside two weeks. If you need a weekend to think about it, plan on losing the ones you like most.
The other end of that record is worth knowing too. 12 of those sales took more than sixty days. Houses that sit are usually priced wrong, and a house that has been sitting is the one place a buyer still has room to negotiate.

Look at the house, then look at the file
The middle house in this record was built in 1960, and the oldest was built in 1877. Old housing stock means the questions that matter are rarely about the kitchen. Ask about the age of the roof, the boiler and the electrical service. Ask whether there was ever an oil tank in the ground and whether there is paperwork for its removal. Ask whether the house is on a cesspool or a sewer.
Ask what has been added and whether it was permitted. An extension, a dormer, a finished basement or a deck without a certificate of occupancy is the single most common thing that stalls a Long Island closing, and it is cheaper to find it before you are in contract than after.

04
Make the offer properly
An offer is a price, a mortgage amount, a closing timeline and a pre-approval. The price is the part buyers focus on and often the smallest lever. A seller who needs to close in sixty days will take a lower number from a buyer who can do it.
In New York an accepted offer is not a deal. Nothing binds either side until contracts are signed by both, which is why the next step happens quickly or not at all.

05
Inspection, then contract
Get the inspection done in the first week after the offer is accepted. You are looking for the expensive and the structural, not a list of loose doorknobs. On houses of this age, add a termite inspection, and add a tank sweep if there is any suggestion of an oil tank.
Your attorney takes it from there. They review the contract, order the title search, check the certificate of occupancy against what is actually standing, and hold your deposit. Long Island runs on attorneys and a good one earns their fee at exactly this point.

06
Contract to closing
Expect somewhere between six and ten weeks from signed contracts to closing, driven mostly by the lender. The appraisal happens in this window. If it comes in under the contract price, the gap is a negotiation and it is better to have talked about that possibility before it happens.
Do the final walkthrough on the day, not the week before. You are checking that what was there is still there and that what was agreed got done.
What John will not answer, and why
Buyers ask what kind of people live in a given area. A licensed agent cannot answer that, and the restriction is not a technicality. Federal and New York Fair Housing law prohibits steering buyers toward or away from an area on the basis of race, colour, religion, national origin, sex, disability, familial status or the other protected classes, and an agent who answers that question is steering whether they meant to or not.
What you can get instead is everything measurable. Tax bills, what has sold and for how much, how long it took, flood zone, sewer or cesspool, what is permitted. District performance data is published by the State Education Department and demographic data is published by the Census Bureau, and both are better sources than an agent guessing.
Questions people actually ask
How much over asking do houses actually sell for on Long Island?
On John Tiburzi's record of 84 closed sales, 78 of them, or 93 percent, closed at or above the asking price, averaging 105.2 percent of ask. That is his own book of business rather than the whole market, and it is weighted toward the towns he works.
How fast do I need to decide on a house?
Faster than most buyers expect. The middle sale in this record went to contract in 18 days and 33 of 83 sales were under contract within two weeks. Seeing a house the week it lists is usually the difference between having a chance at it and reading about it later.
Do I need a lawyer to buy a house in New York?
Yes in practice. New York is an attorney state, contracts are prepared and reviewed by attorneys, and nothing is binding until both sides sign. Get one lined up before you make an offer rather than after one is accepted.
Why are the taxes so different between two similar houses?
Because assessment, district and any exemptions on the property all move the number independently of what the house is worth. Across 82 of these sales the bill ran from $2,690 to $19,848. Always price a house on the total monthly cost rather than the asking price.
What is a certificate of occupancy and why does it keep coming up?
It is the municipal record that what is built on the property was permitted and inspected. Long Island housing stock is old and heavily altered, so extensions, dormers, decks and finished basements frequently exist without one. It is the most common reason a closing here slips, and it is worth asking about at the first showing.
Start with a conversation, not a house
If you are thinking about buying in the next year, the useful first step is working out what the payment looks like with taxes included and what that buys in the towns you are considering.
