Assumable Mortgage vs. Seller Concessions: Which Saves Colorado Buyers More Money?
Assuming a mortgage and using seller concessions are two of the most powerful tools Colorado buyers have right now, but they are not the same thing. An assumable mortgage locks in a below-market rate for the entire loan term, while seller concessions give you a one-time credit at closing. For most buyers, the long-term math heavily favors the assumable mortgage, often by six figures over the life of the loan.
Here's what you need to know:
What Are Seller Concessions?
Seller concessions are credits the seller pays toward your closing costs or a rate buydown at closing. In Colorado, sellers typically offer 2-6% of the purchase price. Buyers use that money to:
- Pay closing costs (title fees, lender fees, prepaid interest)
- Buy down their interest rate with discount points
- Cover prepaid items like homeowner's insurance or property taxes
A 2-1 buydown uses concessions to temporarily lower your rate by 2% in year one and 1% in year two before it resets to the full market rate. It helps cash flow short-term but does not change your permanent rate.
Seller concessions are a one-time event. Once the money is applied at closing, it is gone. Your rate for the remaining 30 years is whatever you locked in on a new mortgage.
How an Assumable Mortgage Works
An assumable mortgage works differently. Instead of taking out a new loan at today's rates, you take over the seller's existing loan at their original interest rate, balance, and terms. The lender re-qualifies you, you cover the equity gap between the home's value and the loan balance, and you step into a monthly payment that reflects a rate from several years ago.
Every FHA and VA loan is eligible for assumption. It's written into their loan docs. Every. Single. One.
With current rates around 6.65% and assumable rates on Colorado homes ranging from 2% to 4%, the savings are not a short-term benefit. They are locked in for the rest of the loan term.

Comparing the Numbers
Here is where it gets concrete. Take a $500,000 home. A seller with a VA loan at 3.25% is offering something fundamentally different from a seller offering $15,000 in concessions toward a rate buydown.
Scenario A: New mortgage at today's rate with seller concessions
- Loan amount: $500,000
- Rate: 6.80% (market rate after concessions applied to a small buydown)
- Monthly payment: $3,260/month
- The $15,000 concession covered closing costs and reduced the rate slightly from 7.2% to 6.80%
Scenario B: Assumable mortgage at 3.25%
- Loan balance assumed: $500,000
- Rate: 3.25%
- Monthly payment: $2,176/month
- Monthly savings vs. Scenario A: $1,084/month
Over 10 years, the assumable route saves $130,080. Over the full loan life, the total interest savings are $390,094.
The seller concession in Scenario A saves you $15,000 once. The assumable mortgage saves you $1,084 every single month, permanently.

Why Seller Concessions Still Have a Place
Seller concessions are not worthless. There are situations where they make practical sense:
You do not qualify for the assumed loan. VA and FHA assumptions require lender approval. If your debt-to-income ratio or credit score does not qualify, concessions may be your best option on a conventional listing.
The assumable balance is too low. If the seller has been paying their loan down for 15 years, the remaining balance might be $180,000 on a $450,000 home. The equity gap of $270,000 may require a second mortgage or cash that you do not have available.
The rate spread is minimal. If the assumable rate is 5.5% and market rate is 6.2%, the monthly difference is smaller. Concessions might fill a more pressing short-term need.
The point is not that concessions are bad. The point is that buyers often default to asking for concessions without running the math on whether an assumable mortgage exists on that property.
When the Assumable Mortgage Wins
The assumable mortgage wins when:
- The rate spread is large. Right now that means any FHA or VA loan originated between 2020 and 2023, when rates ran 2.5% to 4%.
- You plan to stay in the home for more than 3-5 years. The longer you hold, the more the monthly savings compound.
- The equity gap is manageable with cash, a gift, or a second mortgage.
- The seller is motivated and understands the value they are offering. A seller with a 3% VA loan has a built-in marketing advantage: their home is worth more to the right buyer.
For buyers looking at VA loans specifically, the VA loan assumption process covers qualification, entitlement questions, and what to expect during lender review.
How to Find Homes With Assumable Loans in Colorado
The main challenge is that Zillow and Realtor.com do not flag assumable mortgages. You need to search specifically for FHA and VA properties, then confirm with the listing agent that the loan is assumable.
At /homes, Ryan's team has built a filtered search for Colorado homes with assumable FHA and VA loans, organized by rate and equity gap so you can find the highest-value assumptions quickly.
If you are working with a buyer's agent, ask them to filter on MLS by loan type. Any active FHA or VA listing that has not been refinanced recently is potentially assumable.

The Bottom Line
Seller concessions solve a closing-day problem. Assumable mortgages solve a 30-year problem. When both are on the table, the math almost always favors the assumable mortgage for buyers who intend to hold the home.
In Colorado right now, with rates still above 6%, every FHA and VA listing from 2020 to 2023 is worth evaluating for the assumable loan first. The concession can always be negotiated. The rate cannot.
Frequently Asked Questions
Can I get both an assumable mortgage and seller concessions on the same deal?
Yes. A seller with an assumable loan can still offer concessions to help cover the equity gap or closing costs. These are separate negotiations. In this case, the concession might be applied toward your down payment on the equity gap rather than a rate buydown, which is often a more useful application.
Do seller concessions affect my ability to qualify for an assumed mortgage?
No. Your qualification for an assumed mortgage depends on the lender's review of your income, credit, and debt-to-income ratio. Seller concessions at closing do not impact that approval process.
How much do sellers typically offer in concessions in Colorado?
Colorado sellers typically offer 2-3% of the purchase price in concessions. On a $500,000 home, that is $10,000-$15,000. In a buyer's market concessions can go higher, and in a competitive market sellers often offer less or nothing.
Is assuming a mortgage slower than getting a new loan with seller concessions?
Yes, generally. A new mortgage with seller concessions closes in 30-45 days. A mortgage assumption typically takes 60-90 days because the assumption goes through the original lender's assumption department, which is a slower process than standard underwriting. Plan accordingly when submitting offers.
Are there Colorado homes where both an assumable loan and seller concessions are available?
Yes. A seller with a VA loan who also agrees to cover closing costs is offering both. In practice, sellers with low-rate assumable loans are less likely to offer large concessions because the low rate already justifies a higher offer price from a buyer who understands the math.
