About duplexes in Longmont

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.

Full Duplex or Half Duplex: Which One Are You Buying in Longmont?

  • Full duplex (two units, one deed). You own both sides. Live in one, rent the other, and the rent pays part of your mortgage. This is house hacking, and Longmont is one of the Front Range markets where the numbers still work.
  • 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.

Financing a Duplex in Longmont

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.

What to Check Before You Buy a Longmont Duplex

  1. Separate meters. Two electric and two gas meters make renting the other side simple. One shared meter means a lease that splits the bill.
  2. 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.

How to Buy a Duplex in Longmont

  1. Get pre-approved for the right loan. Two-unit owner-occupied, or single-family for a half duplex. It changes the down payment and the rent that counts.
  2. Set the alert. Duplexes in Longmont sell to the buyer who sees them first. A Kenna alert fires the hour a duplex lists.
  3. Tour both units. Tenant-occupied units need notice; a Kenna agent arranges it with the listing agent.

A duplex is two units on one lot, with one deed in most cases. A townhome has its own lot and its own deed. Duplex owners share a structure.
