How to Find Assumable Mortgage Homes in Colorado — A Step-by-Step Guide for 2026
Assumable mortgages are not advertised. You will not see "assumable VA loan at 2.75%" in the listing description on Zillow or Realtor.com. The homes exist — there are thousands of them on the Colorado Front Range — but you have to know how to surface them.
Here is exactly how to do it.
What an Assumable Mortgage Is (and What It Is Not)
When a homeowner has a FHA or VA loan, a qualified buyer can take over that loan exactly as it exists. Same interest rate. Same remaining balance. Same terms. The lender does not get to reset anything to market.
For context on why this matters: a buyer assuming a $380,000 VA loan at 2.875% has a monthly payment of about $1,578. A buyer taking out a new conventional $380,000 loan at 6.875% pays about $2,497 per month. The monthly difference is $919. Over three years, that is $33,084.
The loans that are assumable in 2026 are FHA and VA loans only. Conventional loans are not assumable. If a seller has a conventional mortgage, there is no loan to take over.
Step 1: Search a Platform That Shows Loan Type
The first practical step is using a search tool that surfaces assumable loans instead of burying them.
assumableguy.com aggregates active FHA and VA listings across the Colorado Front Range, including Colorado Springs, Denver, the Douglas County suburbs, the northern Front Range, and the western slope. The platform shows the existing loan rate on each property, estimated monthly payment, and the gap you would need to cover above the current loan balance.
Filter by rate to find homes where the savings are biggest. A loan originated in 2020 at 2.5% saves you more than one from 2022 at 3.75% — both are worth exploring, but the 2020 loan has a larger dollar advantage.
Step 2: Ask the Right Question Before Touring
A large portion of assumable opportunities are not listed as assumable, and sellers often have not been told that assumption is an option. The question that opens deals is simple: "Does the seller have an FHA or VA loan, and are they open to assumption?"
Ask it of the listing agent before you set foot in the home. The answer takes 30 seconds to find and tells you whether this property is worth pursuing on these terms.
If the agent does not know, ask them to find out. If the seller does not know what loan they have, ask the agent to check the most recent mortgage statement. The loan type is on the statement.
Step 3: Understand the Gap Before You Fall in Love
Every assumable deal has a gap: the difference between the current loan balance and the purchase price. If the home is $480,000 and the loan balance is $320,000, your gap is $160,000. You need to cover that with cash, a second mortgage, or a combination.
This is where a lot of buyers get stuck. Do the math before you write an offer.
Second mortgages for gap financing are available but carry higher rates than the primary loan — typically 7% to 9% in early 2026. A $100,000 second at 8% over 10 years adds about $1,213 to your monthly payment. Add that to your assumed loan payment and compare the total against what you would pay on a new conventional loan for the full purchase price.
Often the math still strongly favors assumption, especially on loans originated before 2022. Sometimes on smaller gaps, the numbers favor assumption even after accounting for a full second mortgage on the gap.
Do the calculation on every home you are serious about.
Step 4: Get Pre-Verified for Assumption
A standard mortgage pre-approval letter does not mean anything in an assumption transaction. You need a servicer who handles assumptions to review your file and issue a conditional approval.
Get this done before you write an offer. It takes time — servicers move slower on assumptions than on new originations — and having documentation in hand before you make an offer significantly increases your credibility with the seller.
If you do not know a lender who processes assumptions, Ryan Thomson at Keller Williams works with a shortlist of Colorado servicers who have experience closing them.
Step 5: Write the Offer Knowing the Timeline
Assumptions take longer than conventional purchases. Plan for 45 to 90 days from accepted offer to close. The servicer has to verify the existing loan, approve the buyer, and process the assumption paperwork. VA assumptions have additional steps if entitlement substitution is involved.
Your offer should include realistic timelines. A seller who expected a 30-day close and gets a 75-day estimate will have concerns. Address the timeline in your offer, not in response to an objection.
Include language that extends the close date if the servicer processing is delayed beyond your control — this protects you from losing your deposit if the servicer is slow.
