Why multi-family deals die over a single tenant
Retail buyers need every unit to behave. Access for the appraiser, estoppel paperwork that reads cleanly, rent that shows up in a bank statement. A multi-family property with one uncooperative tenant cannot deliver that, which is why the financed buyer pool for these houses is far smaller than owners expect.
That constraint does not apply to us. We take the multi-family with the tenants it has, and whatever the difficult unit turns into afterward is our time and our expense.

Converted and undocumented Shirley multi-family houses
Long Island is full of houses that became two-family houses at some point without the paperwork ever following. A finished basement with its own entrance. A mother-daughter setup rented for decades. An attic apartment somebody built a long time ago.
It matters at sale time because a lender and a title company look at what the municipality has on record, not at what is actually there. That is where retail multi-family deals stall. We buy these houses knowingly, and an unpermitted conversion is a condition we price rather than a reason to walk.
Why local knowledge changes the number
A house on Johns Neck Road. A house on Seymour Drive. Both in Shirley, bought and paid for by us.
Shirley is roughly 26,360 people in Suffolk County, ZIP 11967, and the housing stock is mostly ranch, cape cod, hi-ranch. Around William Floyd Parkway and the Smith Point Bridge, most of it is old enough that the mechanicals are on their second or third life. The Mastic-Shirley 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 Suffolk County for 15+ years. We know what the William Floyd 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.
Rent rolls, mixed units and the real numbers
Multi-family owners often delay calling because the paperwork is a mess. Leases that ran out years ago, rent taken in cash, a relative in one unit paying something informal, a deposit that was spent long before anybody thought about selling.
None of that disqualifies the house. What is worth telling us at the start is anything a court has already been asked to decide about a tenant, because that affects sequencing and we would rather know now than at the closing table.
What experience with multi-family actually buys you
A multi-family sale is rarely one problem. It is the tenants, the paperwork, the condition and sometimes the municipality, all arriving together, and owners are rarely in a position to project-manage them.
That is the part we are genuinely useful for. We know how a Suffolk County multi-family transaction sequences, which issues a title company will actually raise, and which professional to call when it needs one. We have bought buildings at every stage of this.
What the two paths cost in Shirley
These are the two routes open to you with a multi-family property, priced against what Shirley houses actually sell for.
Work it against Shirley's own numbers. The median sale here is $549,990. A 5% commission on that is $27,500, and seller closing costs of about 2% add roughly $11,000. Those are costs we can cover on our side. That is $38,499 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 Shirley the median house takes about 43 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 88 to 103 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 | $549,990 (Shirley median) | Our written offer |
| Commission | −$27,500 | None |
| Seller closing costs | −$11,000 | We can cover them |
| Repairs before listing | Out of pocket | None |
| Cleanout | Yours | Ours |
| Showings | Until it sells | One visit |
| Listed to signed contract | 43 days (Shirley 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 | 88 to 103 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 | $511,491 | 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.
The condition of a Shirley multi-family property
Owners maintain a rented building to the standard of keeping it rented, which is a sensible way to run a multi-family and a poor way to prepare one for a retail buyer. The kitchens are functional, the systems are old, and the whole thing shows its age the moment an inspector walks through.
That gap is exactly where financed sales come apart and exactly where we are comfortable. Tell us plainly what needs doing and it goes into the offer.
What you do not pay when you sell a multi-family property
Every line below is a cost of listing a multi-family property the retail way that simply does not arise here.
- Agent commission
- $27,500 at 5% of the Shirley median none
- Seller closing costs
- About $11,000 on a $549,990 sale. We can cover these. none
- Repairs to make it listable
- Whatever the house needs, paid up front none
- Cleanout and removal
- Paid per load, before a single buyer walks through none
- Carrying costs while it waits
- Taxes, insurance and utilities for the 88 to 103 days of finding a buyer and waiting on their mortgage none
When listing the building is the better move
The comparison that matters is our offer against what a multi-family listing actually produces, after commission, after the repairs a buyer demands, after the months of carrying a building with a unit that is not paying.
The median house in Shirley sold for $549,990 and took about 43 days to go under contract, then another 45 to 60 days waiting on the buyer's mortgage. That is 88 to 103 days in total, for a house that was ready to show on day one. We will go through both columns with you, and we are not troubled if the conclusion is that you should list.
Common questions
Do you buy two-family and three-family houses in Shirley?
Yes. Two-family, three-family and converted houses are a regular part of what we buy, occupied or vacant, and we do not need every unit shown before making an offer.
The conversion was never permitted. Can you still buy it?
Yes. Unpermitted conversions are common here and we buy them knowingly. What the municipality has on record is something we deal with after closing rather than something you have to resolve first.
One unit pays and one does not. Does that kill the deal?
It changes the number, not the answer. We buy buildings with arrears in one or more units and take the arrears situation on ourselves after closing.
Can you make an offer if a tenant will not let you in?
We will not ask you to force entry on anybody. Show us what the tenants allow, tell us what you know about the rest, and we will still put a written number on the Shirley multi-family.
What happens to the leases and the deposits?
The leases run with the building and the deposits transfer at closing through the attorneys in the normal way. You do not need to reconcile anything with a tenant beforehand.
