Condo vs. brownstone
A condo and a brownstone can have dramatically different ownership economics. With a 2–4 unit property, rent from the additional apartments can help pay your mortgage while you build equity in the entire building—not just a single apartment. Enter your numbers below to compare true monthly cost and long-term equity.

Over 10 years, brownstone equity is $670,015 higher than the condo on these assumptions.
“The brownstone in this scenario costs $1,000,000 more than the condo, but after receiving approximately $6,650/mo in net rental income, your effective monthly housing cost is actually $903 lower.”
Your tenants could cover approximately 40% of your monthly brownstone property carrying expenses.

You own the entire building and lot — not just a single apartment.
Growth compounds on the full multi-family structure value.
No condo common charges or condo-board budget restrictions.
List price alone can be misleading. A brownstone may cost more up front, yet after collecting net rent from the other units your effective monthly housing cost can be lower than a condo with high common charges. Conversely, weak rents or heavy operating costs can favor the condo. The calculator on this page is built to surface that tradeoff clearly.
Your tenants help offset mortgage principal, interest, property taxes, building insurance, and operating expenses.
Instead of building equity in a single apartment, you own the entire building, land, and lot—creating a larger base for appreciation.
When the property appreciates, that growth compounds on the total value of the multi-family structure, not just one unit.
There are generally no condo common charges or condo-board restrictions controlling your monthly budget the way co-ops and condos often do.
True monthly cost: For the condo, add mortgage P&I, taxes, common charges / HOA, insurance, and a maintenance reserve. For the brownstone, add P&I, taxes, building insurance, maintenance reserve, and owner-paid utilities—then subtract net rental income after vacancy.
Long-term equity: Switch the horizon between 5 and 10 years to compare projected property value, remaining mortgage, principal paid down, appreciation, cumulative net rent (brownstone), and owner equity. A higher monthly payment can still win if it builds substantially more equity over time.
Rental leverage: The tenant-coverage percentage estimates how much of the brownstone's carrying costs rent can offset. Even partial coverage changes the affordability conversation versus a condo where you pay 100% of carrying costs yourself.

Yes. If net rent from the other units is strong enough, effective out-of-pocket cost can undercut a condo with high common charges—even when the brownstone's purchase price is higher.
Mortgage principal & interest, property taxes, common charges / HOA, homeowners insurance, and an annual maintenance reserve percentage converted to a monthly amount.
Mortgage P&I, taxes, building insurance, maintenance reserve, owner-paid utilities, then an offset for net rental income after vacancy. Closing costs and appreciation assumptions feed the equity projection.
