About the area

Why Deer Park sellers call us.

Deer Park is the hamlet in the Town of Babylon between the Long Island Expressway and the Southern State, with Deer Park Avenue running through the middle, the railroad station at the south end, Commack Road and the old Pilgrim State Hospital grounds on the east, and Wyandanch and Dix Hills on either side. It was farms and the hospital’s land until the war, and almost all of it was built between 1950 and 1965: capes and ranches on 60 by 100 lots, split levels toward Dix Hills, and the attached houses near the station. The families who bought then worked at Pilgrim State, at Grumman, at Republic in Farmingdale, and the ones who are still in the houses are in their eighties. Their children are in Florida and the Carolinas. The houses have a 1962 kitchen, a basement finished for a tenant, a cesspool, and sixty years of a family inside, and the taxes on a Deer Park cape now run past twelve thousand dollars a year.

The cape your parents bought in 1958 and the children in Florida

The most common Deer Park call is an estate. A cape on a street off Grand Boulevard bought in 1958 when the development was new, paid off by 1980, with the original kitchen, a bathroom with pink tile, a basement finished in 1971 with paneling, a boiler that was converted from oil with the tank still in the yard, and sixty years of belongings. The children are in Port St. Lucie and Charlotte, the Suffolk County Surrogate’s Court in Riverhead has the file, and nobody wants to drive out to empty the house. We buy it full, as it stands, wait for the letters, and each heir signs with a notary where they live.

The basement apartment and the Town of Babylon

Deer Park basements are finished, and a large share have a kitchen, a bathroom, a side door and a tenant. The Town of Babylon has an accessory apartment permit, and almost none of these units ever went through it. A financed buyer’s appraiser notes the second kitchen, the lender wants it gone or permitted, and the sale dies. A neighbor’s complaint brings a town inspector and a citation. We buy the house as its legal layout, price the apartment as what it actually is, handle the tenant on terms you set, and the town file is ours after closing.

Behind on the mortgage since the refinance

Deer Park was hit hard in the subprime years, and a good number of houses carry a 2006 loan that was modified once and is behind again, with a Suffolk County Supreme Court case that has been adjourned for years. Suffolk foreclosures are among the slowest in the state, and that delay is the opening. Until the referee’s sale in Riverhead actually happens, you own the house and can sell it. A cash closing before the date pays the bank from the price and keeps whatever equity is left with you.

Cesspools, tanks and the county health department

Deer Park is not sewered, and every house has a cesspool or a septic system that a lender wants inspected and often replaced before closing. A new system in Suffolk needs a county health department permit and weeks of waiting. Add the oil tank left in the yard after a 1990s gas conversion and a bank deal has two reasons to stall. We buy with the cesspool as it is and the tank in the ground, price both as lines on the offer, and pull the permits ourselves after closing.

Where listing still wins in Deer Park

A cape with a legal layout, a new cesspool and a current boiler, with no deadline, should be listed, and we will say so. First time buyers priced out of Nassau are waiting for exactly that house. Where a cash sale wins is the estate full of belongings, the basement apartment the town has not seen, the loan with a referee’s date, the failed cesspool, or the owner with a closing in Florida that cannot move.

What we buy in Deer Park

Capes, ranches, split levels and colonials, two families, houses with an accessory apartment legal or not, houses in foreclosure at any stage before the auction, houses with a failed cesspool or an oil tank, mixed use buildings on Deer Park Avenue, estates in any condition, and vacant lots. We do not buy cooperative apartments. If you own something unusual, call anyway.

North of the expressway, the station blocks, and the Pilgrim State edge

Deer Park is priced by which side of the Long Island Expressway you are on and how close to the station. The streets north of the expressway toward Dix Hills are splits and colonials on wider lots and the top of the hamlet. The capes and ranches between the expressway and the Southern State, off Grand Boulevard and Carlls Path, are the center of the market. The blocks by the station and the attached houses along Deer Park Avenue are the entry point. We build the offer from sales on your streets, with the comparable addresses on the sheet, and we show you which band your house is in before we show you the number.

Suffolk estates, the Riverhead court, and heirs who are not on Long Island

A Deer Park estate goes through the Suffolk County Surrogate’s Court in Riverhead, and the heirs are almost always in Florida or the Carolinas rather than down the street. We write the offer while the file is open, the estate attorney gets the letters, and each heir signs with a notary where they live. New York takes an estimated income tax from out of state sellers at closing, credited on the return, and the sheet shows it so the net to the estate is known before anyone signs. The house stays full until the day we close.

How a sale like this goes in Deer Park

Off Grand Boulevard, 1958: a Cape With a Pilgrim State Pension Behind It, a Basement Tenant Since 2011, a Cesspool That Failed in April and Two Children in Port St. Lucie and Charlotte

Their parents bought the cape off Grand Boulevard in 1958, the year their father started as an attendant at Pilgrim State. He finished the basement in 1971. Their mother rented it to a tenant in 2011, after he died, for cash, with a side door and no permit. She died in the house in February 2025 at ninety one. The son lived in Port St. Lucie, the daughter in Charlotte. The cesspool failed in April, during the first showing.

The daughter listed it in March. The first buyer was FHA. The appraiser found the basement kitchen and the lender asked for it removed. The second buyer's attorney asked for a cesspool certification and the county said a new system, with a permit that would take six weeks. The agent said the tenant had to go and the system had to go in before anyone would finance it. The estate account had eight thousand dollars.

The estate attorney in Babylon village called us in May. The offer was written on the cape as it stood: the basement as a basement with the tenant staying ninety days on terms the two of them set, the cesspool as a line, an oil tank in the yard, the 1958 kitchen, a roof from 1998, and sixty seven years of an attendant's household as a cleanout line. One page, with the sales on the neighboring streets listed by address, sent to Florida and North Carolina the same evening.

Both signed with notaries. We closed in June at an attorney's office on Deer Park Avenue. The county permit was pulled in July. The daughter took the photographs and her father's hospital badge. What she said was that the agent had three jobs for them before anything could happen, and the only job had been to sign.

Common reasons Deer Park sellers call us.

A cape off Grand Boulevard your parents bought in 1958, with the pink tile and sixty years inside

Heirs in Port St. Lucie and Charlotte, a Riverhead Surrogate's file, a house that is full. We buy it full and each heir signs where they live.

A basement apartment with a side door the Town of Babylon has never seen

No lender counts it. We price it as what it is, buy the house as its legal layout, and the town file is ours after closing.

A 2006 loan modified once and behind again, with a case in Riverhead since 2019

Suffolk foreclosures take years and that is the opening. A cash closing before the referee's date pays the bank and leaves the equity with you.

A cesspool that failed and a county permit that takes weeks

We buy with the system as it is, price the replacement, and pull the Suffolk health department permit ourselves.

An oil tank in the yard from the 1995 gas conversion

A bank wants it pulled and tested first. We buy with it in the ground and the soil result is our risk.

Property taxes past twelve thousand dollars on a pension

We close in about two weeks and the tax bill stops being yours on the day the deed records.

A tenant in the basement who stopped paying

Suffolk landlord tenant court is slow. We buy on the rent actually arriving and the case comes with the house.

A move to the Carolinas with the new closing already set

We set the Deer Park closing around it, about 14 days out, and nothing waits on a bank.

Frequently asked questions about selling in Deer Park.

How fast can you buy a Deer Park house?

Send the address or call (516) 964-7222. We come out within a couple of days, write a number within 24 hours with the Deer Park comparables on it, and close at a Suffolk attorney's office on your date. About 14 days is typical when the title is clean, longer with an estate or a lien.

The basement has a kitchen and a tenant. Does the town have to know before I sell?

Not to sell to us. A lender's appraiser flags the unit and the sale dies there. We buy the house as its legal layout, price the apartment as what it is, and the Town of Babylon file, if there is one, comes to us at closing.

The cesspool failed. Do I have to replace it first?

Not for us. A financed buyer's lender wants a certified system, and a new one needs a Suffolk County health department permit and weeks. We buy with the cesspool as it is, price the replacement on the sheet, and pull the permit after closing.

The bank filed in Riverhead years ago. Is it too late?

Almost never. Until the referee actually sells the house you own it and can sell it. We get the payoff from the bank's attorney, price the house against it, and close before the date so the case is discontinued and the rest is yours.

My sister is in Florida and I am in North Carolina. Do we have to come to Deer Park?

No. We coordinate with the Suffolk County Surrogate's Court file and your estate attorney, a neighbor lets us in, and each of you signs with a notary where you live. The house stays full until closing.

Would listing do better?

Often, and we say so. A cape with a legal layout, a new cesspool and no deadline usually nets more listed. Ours is the better route when the house is an estate full of belongings, the basement has a tenant, a loan has a date, the cesspool failed, or you have a move to make.

How do you figure the number?

Recent sales on your streets in Deer Park, minus the work, the cesspool, the tank, the apartment as the town sees it, carrying and resale, and our margin. Each is a line on the sheet and the sheet is yours before you sign.

What comes off the price?

Your payoff, any Suffolk tax lien or town balance, and the New York State transfer tax, each itemized on the offer. No commission, no fees, we pay our own closing costs.

We also buy in nearby Long Island neighborhoods.
