Brooklyn Mortgages: Two-Family Brownstones, Condos and High-Balance Loans
Updated October 2026
Brooklyn's signature deal is the two-family brownstone: you occupy one unit, rent the other, and let documented lease income help carry the mortgage. Because Kings County is in the 2026 high-cost tier, your one-unit conforming ceiling is $1,249,125 and two-unit limits are set higher still, which keeps a large share of Park Slope, Bed-Stuy and Ditmas Park contracts inside agency financing rather than jumbo.
Making Rental Income Count
Underwriters do not accept a seller's estimate of what the garden apartment could rent for. Bring documentation:
- Executed leases for any occupied unit, plus a rent roll
- An appraisal with a comparable rent schedule for the subject property
- Evidence of a legal second unit, since an unpermitted basement apartment will not be counted
- Reserves, which run higher on 2-4 family files than on a single-family purchase
A typical vacancy factor of 25% is applied to gross market rent, so a $3,000 unit supports qualifying income closer to $2,250 per month.
Brownstone Versus Condo Costs
| Factor | Two-family brownstone | New-construction condo |
|---|---|---|
| Qualifying help | Documented rental income from the second unit | None, owner-occupied only |
| Mortgage Recording Tax | 1.80% to 1.925% of the loan | 1.80% to 1.925% of the loan |
| Mansion Tax | 1% once price reaches $1,000,000 | 1% once price reaches $1,000,000 |
| Ongoing budget | Roof, boiler, facade and landlord duties | Common charges plus possible assessments |
| Project review | Not required | Budget, reserves and owner-occupancy review |
Both paths close the New York way, through counsel with table funding on the day of closing. If you later refinance, a CEMA assignment limits recording tax to new money only, which on a $900,000 Brooklyn loan is often the single largest savings in the transaction.
Programs and Property Taxes
First-time buyers under the income caps can pair SONYMA Achieving the Dream or Low Interest Rate financing with a DPAL of 3% of price up to $15,000. Once you close, file for STAR, or Enhanced STAR if you are 65 or older and income-eligible.

Editorial Methodology & Primary Sources
Verification date: Not recorded; check the primary source and lender timestamp before relying on an estimate.
Rate comparisons use participating lender feeds, not a whole-market survey or guaranteed offers. Freddie Mac PMMS is a market benchmark, not a personalized quote. Calculator models rely on published regulatory formulas and disclosed assumptions rather than fabricated first-person loan testing.
Monthly principal and interest use the amortization formula P × r / (1 − (1 + r)−n), where r is the monthly note rate and n is the number of payments; at zero interest use P / n. PITI adds monthly property taxes and homeowners insurance; PMI is separate. APR includes applicable finance charges under Regulation Z and is not the note rate used for payments. Compare lender Loan Estimates for actual APR and fees.

- U.S. Department of Housing and Urban Development (HUD / FHA) — FHA program guidance.
- U.S. Department of Veterans Affairs (VA) — VA loan eligibility and benefits.
- Freddie Mac Primary Mortgage Market Survey (PMMS) — published rate benchmarks.
- U.S. Census state tax collections — state property tax benchmarks; confirm parcel-specific assessments and exemptions with the state revenue department and local assessor.
The payment snapshot uses illustrative annual taxes of 1% of home price, $1,200 insurance and 0.5% PMI below 20% down, not verified local quotes. Other calculators disclose their inputs and assumptions. Published guidance and lender feeds may change independently; confirm current program rules, taxes and offers before a decision.
