Buying 2 to 4 Units in Boulder

• House hacking with 3.5 percent down. FHA lets you buy a 2 to 4 unit property in Boulder as an owner-occupant with 3.5 percent down and count 75 percent of the rents toward qualifying. VA does it with zero down. Conventional owner-occupied duplexes go at 5 percent.
• The numbers. Rents, vacancy, taxes, insurance, water, maintenance and management. We build the sheet from the seller's leases and the actual bills, not the listing's pro forma.
• Leases and tenants transfer. You buy the leases in place. Colorado's landlord-tenant rules, security deposits and notice periods apply from day one.
• Zoning and legal units. A "duplex" in Boulder with one meter and no permit is a single family home with a problem. We check the zoning and the permit history.
• Separate systems. Separate meters, furnaces and water heaters make a building easier to run and worth more. Shared systems mean you pay the utilities.

Boulder Questions

Can I buy a fourplex with an FHA loan in Boulder?

Yes, as an owner-occupant with 3.5 percent down, up to the four-unit FHA limit for the county. The property has to pass the FHA self-sufficiency test on 3 and 4 units.

What do multi-family homes rent for in Boulder?

It depends on the unit size and the block. Your Kenna agent pulls the current rents from the seller's leases and the market rents from the comps before you write.

Do I need a property manager?

Not for a duplex you live in. For 3 or more units or an out-of-town owner, a Boulder manager runs 8 to 10 percent of rents and earns it.

Can I see a Boulder multi-family property today?

Yes. Call or text 303-955-4220 and a Kenna agent sets the showing with the tenants, 7 days a week.
