Short answers

How much can I borrow to build apartments?

Under HUD's 221(d)(4), up to 87% of cost for market-rate projects and 90% for affordable ones, if the income covers the debt at 1.15 or 1.11. Banks are held to 80% of value and, to avoid HVCRE treatment, borrower capital of 15% of the as-completed value. Debt funds lend what they negotiate.

How long does it take to build an apartment building?

Buildings with 20 or more units that finished in 2025 took an average of 19.1 months from start to completion nationally, after 2.6 months from permit to start, according to the Census Bureau. The Northeast averaged 23.5 months; the Midwest 14.9.

Is a HUD construction loan fixed or floating?

Fixed. A 221(d)(4) sets one rate for construction and a term of up to 40 years, with no refinance at completion. Bank and debt fund construction loans usually float over SOFR and need a take-out loan.

Is this site affiliated with HUD or a bank?

No. It is operated by Janover Capital LLC, a commercial mortgage firm, and is not affiliated with HUD, FHA, the Census Bureau, the Federal Reserve or any lender.
