Low Down Payment Mortgage Programs for Owner-Occupied Duplexes
Owner-occupied duplex buyers in Denver do not always need 20 percent down. FHA allows 3.5 percent, VA allows zero for eligible buyers, and some conventional and Colorado assistance programs can reduce the cash you need to close and still protect your reserves after closing.

The core programs
FHA 3.5% and VA 0%: the two lowest-cash routes
FHA is the program most owner-occupied duplex buyers start with. At 3.5% down with a credit score of 580 or above, a duplex avoids the extra self-sufficiency test that applies to three and four unit FHA purchases, although mortgage insurance and FHA appraisal condition standards still apply. Rental income from the other unit may help you qualify, typically counted at 75% of existing or appraised rent — the full mechanics are in the FHA house hacking guide.
VA is the lowest-cash route of all for those who qualify: 0% down on up to four units for eligible veterans and service members, with no monthly mortgage insurance. A VA funding fee applies unless you are exempt, and the property must pass VA appraisal standards. If you have any VA eligibility, have it checked first — the saving compared with even a 3.5% down payment is substantial. Details are in the VA house hacking guide.
Conventional and assistance
Conventional low-down options and Colorado assistance
Conventional financing on a duplex typically requires 15–25% down for small multifamily, so it is not usually the lowest-cash route — but selected owner-occupant conventional programs can, in some cases, allow lower down payments depending on income, first-time buyer status and lender overlays. Treat any low-down conventional quote as program-specific: confirm the unit count, income limits, mortgage insurance cost and reserve requirements in writing before you rely on it in an offer or a cash-to-close plan.
Colorado buyers should also check the Colorado Housing and Finance Authority — CHFA — which offers down payment assistance programs for eligible buyers who meet its income, credit and homebuyer education requirements. Assistance amounts, eligibility and property rules change and vary by program, so this page does not quote figures: check current eligibility directly and through a participating lender. The full comparison across every route sits in house hacking financing options for Denver buyers.
Cash beyond down payment
The cash you need beyond the down payment
The down payment is only part of cash to close. Budget also for lender and title closing costs, prepaid taxes and insurance, an appraisal and inspection, any repairs needed before tenants move in, moving costs, and — most importantly — a reserve you do not spend. Lenders on small multifamily loans may also require reserves after closing. Buyers who spend every dollar reaching closing are exposed the moment a unit sits empty for a month or a water heater fails in the first winter.
A practical way to plan is to total four buckets separately: down payment, closing costs and prepaids, immediate property costs, and a protected reserve. Then test that total in the house hacking calculators alongside the monthly payment at conservative rents. If the deal only works by emptying the reserve bucket, it is not yet a low-risk deal, however low the advertised down payment percentage looks in a listing or a lender advertisement.
Illustrative example
An illustrative cash-to-close example for a Denver duplex
The following example is illustrative only, using the published October 2026 snapshot on this site — a Denver median price of about $546,000 — and it is not a quote or a prediction for any specific property. At 3.5% down, the FHA down payment on $546,000 is about $19,110. Closing costs and prepaids might add a further sum in the low tens of thousands depending on lender, taxes and insurance, and a prudent reserve would sit on top of that again, untouched, after you receive the keys.
The lesson of the example is the ratio, not the exact total: on a low-down purchase, closing costs and reserves can together rival or exceed the down payment itself. That is why Jeffrey walks first-time duplex buyers through a full cash-to-close estimate with their lender before touring, and why the beginner sequence in how to start house hacking in Denver puts the loan and budget steps ahead of the property search, not after an offer is accepted.

FAQs
Questions, answered
Can I buy a Denver duplex with only 3.5% down?
Yes, with an FHA loan, if you live in one unit as your primary residence and meet credit and lender requirements. FHA allows 3.5% down with a credit score of 580 or above on one to four unit properties. Duplexes are exempt from the extra self-sufficiency test that applies to three and four unit FHA purchases.
Can I buy a duplex with no down payment?
Eligible veterans and service members can use a VA loan at 0% down on up to four units, provided they live in one unit. A VA funding fee applies unless exempt, and closing costs and reserves are still required. Buyers without VA eligibility should compare FHA and assistance options instead of expecting a zero-cash purchase.
What is CHFA and can it help with my down payment?
CHFA is the Colorado Housing and Finance Authority. It offers down payment assistance programs for eligible Colorado buyers who meet income, credit and education requirements, usually through participating lenders. Program amounts and rules change, so check current eligibility directly rather than relying on figures quoted on older websites or social media.
How much cash do I need besides the down payment?
Plan for closing costs, prepaid taxes and insurance, appraisal and inspection fees, immediate repairs, moving costs and a reserve kept after closing. On a low-down purchase those items can together rival the down payment. Get a full cash-to-close estimate from your lender for the specific property before you write an offer.
Does a low down payment mean a worse deal?
Not necessarily, but it means a higher loan balance, a higher monthly payment and usually mortgage insurance on FHA or conventional loans. The deal still has to work at conservative rents with a reserve intact. Low down payment is a way to start sooner, not a substitute for a property whose numbers work.
