What happens to a listing when the system fails
The frustrating part is the gap between the problem and the reaction to it. A cesspool is a solvable piece of work, done by contractors who do it every week, and yet it clears a room of retail buyers faster than almost anything else.
That is because nobody in a conventional sale can size it. The seller does not know, the buyer does not know, the agent does not know, and the only way to find out is for somebody to spend money. So the deal stalls over the cesspool, and stalled deals rarely restart.

What we take on when the system has failed
The useful thing we bring to a failed cesspool is proportion. Homeowners get handed a figure by the first company they phone, assume that is the figure, and make a decision about their house on the strength of it.
We do this constantly. We can look at the age of the house, the lot, where the system sits and what the ground is like in that part of Nassau County, and form a realistic view of what the cesspool actually needs. Sometimes it is smaller than you were told. Tell us what happened and we will tell you plainly what usually comes next.
Why local knowledge changes the number
A four-bedroom on State Street. In Valley Stream, bought and paid for by us.
Valley Stream is roughly 40,634 people in Nassau County, ZIP 11580, and the housing stock is mostly cape cod, colonial, tudor. Around Green Acres Mall and Sunrise Highway, most of it is old enough that the mechanicals are on their second or third life. The Valley Stream 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 Valley Stream Central High 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.
You do not need to replace it before you sell
Do not spend money on an inspection or a pump-out for our sake. We are asking for neither.
If the cesspool has already been looked at, bring whatever the contractor wrote down and it saves a conversation. If it has not, we would rather walk the property ourselves and price the system from what we can see. We are buying the cesspool along with the house, so there is nothing you need to prove to us about it beforehand.
The county health department, and why it matters here
Replacing a waste system is a project rather than a repair. It means design, approvals, excavation, and a yard that looks like a construction site for a while, and on some lots the layout makes it considerably harder than on others.
What is permitted and what it costs turns on the specifics of your parcel, and the two places to get a real answer are your county health department and a sanitary contractor who has walked the property and looked at the cesspool. What we can tell you is that we buy houses with failed cesspools without needing any of that settled first.
How we arrive at a number on a house with a failed cesspool
On a house with a failed cesspool 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 Valley Stream median of $775,000 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 Valley Stream the stock is largely cape cod and colonial, and on houses that age the mechanicals are usually the expensive part rather than the cosmetics.
- How long we will hold it. The median Valley Stream house goes under contract in about 33 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.
Why cash matters when the cesspool has failed
On a financed sale, somebody has to make the cesspool right before the money moves, and that somebody is almost always the seller. Plenty of people agree to it because they think there is no alternative.
There is. We buy with the failed system in place, at our cost, and we close on the date you pick. Nothing about the cesspool has to be resolved beforehand, because there is no underwriter sitting behind us asking for it.
What you do not pay when you sell a house with a failed cesspool
These are the costs of putting a house with a failed cesspool on the market through an agent. None of them apply when you sell to us.
- Agent commission
- $38,750 at 5% of the Valley Stream median none
- Seller closing costs
- About $15,500 on a $775,000 sale. We can cover these. none
- Repairs to make it listable
- Whatever the house needs, paid up front none
- Cleanout and removal
- Charged by the truckload, and done before the first showing none
- Carrying costs while it waits
- Taxes, insurance and utilities while you spend 78 to 93 days finding a buyer and waiting for their loan none
What to do next about the cesspool at your Valley Stream house
New York has disclosure obligations for sellers, and what applies to your situation is a legal question. Ask an attorney about the cesspool before you sell to anyone, ourselves included.
Separately from that: tell us everything. When the cesspool failed, what it did, who has looked at it, what they said. None of it puts us off, and all of it makes the number solid the first time. The deals that fall apart are the ones built on half the story.
Common questions
Do I have to fix the cesspool before you buy a Valley Stream house?
Not at all. No repair, no replacement, no pump-out, no inspection. The condition of the cesspool is priced into the offer, and the offer does not move afterward.
What does a new cesspool or septic system cost?
It turns on the lot, the location and what the county health department requires at your address, so any cesspool figure quoted from a web page is a guess. A sanitary contractor who has walked the property will give you a real answer.
The cesspool backed up but the house is still livable. Is that a failure?
Sometimes a backup is a blockage and sometimes it is the cesspool reaching the end of its life, and telling those apart takes somebody who has opened it up. Either way we buy, and either way it is worth knowing which one you have.
A buyer walked away over the cesspool. Does that hurt my chances with you?
Not at all, and it is how a great many people arrive here. A retail buyer walking over a failed cesspool tells us something about that buyer, not about your house.
Do you buy houses on septic as well as cesspools?
Yes. A great deal of Nassau County is on cesspools or septic rather than sewers, and we buy across all of it. Whatever is in your yard, it does not have to be working for us to buy the house.
