Half duplex (one side, your own deed). You own your side and the land under it; the neighbor owns theirs. It lives like a townhome with a yard and, in many Longmont neighborhoods, no HOA. A party-wall agreement governs the shared wall and roof.
Paired homes and twin homes. Builder names for a new half duplex. Same ownership as above, newer construction, HOA more common.
Separate meters. Two electric and two gas meters make renting the other side simple. One shared meter means a lease that splits the bill.
The party-wall agreement. On a half duplex it decides who pays for the roof, the shared wall and the sewer line. Read it before you offer.
Zoning and rental rules. Longmont zoning sets whether both units rent long-term. Short-term rental rules are separate and stricter.
Current leases and deposits. On a full duplex you inherit the tenant, the lease and the deposit. A Kenna agent gets the lease, the rent roll and the deposit ledger during your review period.
Sound and systems. One furnace or two, one water heater or two, and how much you hear through the wall. The showing tells you; a Kenna agent asks the seller for the rest.
Offer from the numbers. Sold duplexes in Longmont in the last six months plus the real rent set the price. A Kenna agent runs both before you write.

An owner-occupied full duplex qualifies for FHA financing with 3.5 percent down and for conventional financing with 5 percent down, and lenders count a share of the second unit's rent as your income when you qualify. VA buyers finance a two-unit home with no money down. A half duplex finances like any single-family home. A Kenna agent connects you with a lender who writes two-unit loans every week, because the appraisal and the rent schedule are different from a house.
Investors pay for rent, owner-occupants pay for the half they will live in, and the two groups value your property differently. A free Smart Pricing Report prices your Longmont duplex both ways, with three prices and the time frame for each. Call or text 303-955-4220.
