There are properties listed in Williston and Watford City right now carrying mortgages at 2.25%, 2.75%, and 3.25% that a qualified buyer can legally take over at the seller's rate. That information is not on the major consumer portals, it is not a standard field in our MLS, and no listing agent is required to disclose it. So we built the search ourselves: ProvenAssumptions.com shows every listed property in our market with an assumable loan attached, and it shows you the loan itself, not just the house.
The Tool
What does ProvenAssumptions.com actually show you?
Most "assumable loan" pages online are lead capture forms. You put in your email, somebody calls you, and you find out nothing. Ours shows you the numbers before you talk to anyone.
For every listed property with an assumable loan, you can see:
| What you see | Why it matters |
|---|---|
| The seller's interest rate | This is the entire deal. A 2.75% note in a 6.75% market is the difference. |
| The remaining loan balance | Tells you the cash gap you need to cover before you tour the property. |
| Your payment on the assumed loan | The actual principal and interest figure, not an estimate. |
| That payment versus a new loan on the same property | The real side by side, in dollars. |
| Remaining term on the note | A 2021 loan has about 25 years left, so you own it outright five years sooner. |
The Math
How much does assuming a loan actually save?
Here is a real world example using Williston's current median price range. Same property, same buyer, two financing paths.
A home listed at $379,000. The seller bought in 2021 with a VA loan. Original balance was $310,000 at 2.75%. Five years of payments later the balance is approximately $274,300, with about 25 years left on the note.
| Traditional new loan | Assuming the seller's loan | |
|---|---|---|
| Purchase price | $379,000 | $379,000 |
| Loan amount | $360,050 | $274,300 assumed |
| Interest rate | 6.75% | 2.75% |
| Term | 30 years | 25 years remaining |
| Monthly principal and interest | $2,335 | $1,266 |
| Mortgage insurance | Yes, on 5% down conventional | None on a VA note |
| Cash required at closing | $18,950 down | $104,700 to cover seller equity, plus a 0.5% VA funding fee of $1,372 |
The monthly difference is $1,069. That is a 45.8% reduction in payment on the identical property.
Run it across the full term and the number gets harder to ignore. Total remaining principal and interest on the assumed loan is roughly $379,800. On the new 30 year loan at 6.75%, it is roughly $840,600. That is a difference of about $460,800 in lifetime payments, on the same property, for the same buyer, in the same week.
Depending on the spread between the seller's rate and the current market rate, we see payment reductions from the high 20% range on shallower spreads up to 60% on the deepest ones. The 2.25% and 2.5% notes originated in 2020 and 2021 are where the biggest numbers live.
A $1,069 lower payment does not just save money. It changes what you qualify for, because underwriters approve you on payment, not on price. Buyers who assume a low rate note routinely qualify for a property 20% to 30% above what a new loan at market rates would allow them to buy.
The Honest Part
What is the catch on an assumable loan?
There is one, and I would rather you hear it from me than find out at the closing table.
You have to cover the seller's equity
You are taking over the loan balance, not the purchase price. In the example above, that gap is $104,700 and it has to come from cash or separate financing. This is the single most common reason assumption deals fall apart, but it does not have to be. You do not need all of it in cash. We work with several strong local lenders who will write a second lien behind an assumption for buyers with good credit, and while that second carries a higher rate than the assumed note, the blended cost still lands well under today's market. On the example above, a first at 2.75% on $274,300 combined with a second at 9% on the $104,700 gap blends to roughly 4.48%, against a market rate near 6.75%. The number to watch is the term on that second, because a short amortization can absorb the monthly advantage even when the blended rate looks good. That is worth modeling before you write an offer, not after.
Only government backed loans are assumable
VA, FHA, and USDA. Conventional loans are not, in nearly all cases. That is why the inventory is limited and why a search tool matters.
You still have to qualify
The servicer underwrites you on credit, income, and debt to income, generally looking for a 620 or better score and a debt to income ratio around 41% or lower. You do not need to be a veteran to assume a VA loan, but you do need to qualify.
It takes longer
Assumptions commonly run 45 to 90 days because they move at the servicer's pace, not the lender's. Plan your closing and your move around that.
Sellers, read this carefully
If a non veteran assumes your VA loan, your entitlement stays tied to that property until the loan is paid off, which affects your ability to use VA financing on your next purchase. You also need a formal Release of Liability from the servicer in writing. A verbal assurance is not protection. Both of these are solvable, but they have to be handled deliberately, before you accept the offer.
An assumable low rate note is a marketing asset most sellers do not realize they are sitting on. In a market where affordability is the buyer's main obstacle, a 2.75% loan attached to your property is a reason for someone to choose your listing over the one down the street. We market it as a feature, because it is one.
Why We Built It
Why does no other brokerage in the state have this?
Because assembling it is tedious and there is no shortcut. Assumable status is not a standard MLS field in our market. Pulling the loan detail behind each listing, verifying the balance and the rate, keeping it current as properties come and go, and presenting it in a way a buyer can actually use takes ongoing work. It is easier to write a blog post about assumable loans in the abstract than to build the list.
We built the list. It refreshes against live inventory across Williston, Watford City, and the surrounding western North Dakota markets, and Cami and the team at Heartland Mortgage can run your qualification against a specific note the same day you find it.
FAQ
Common questions about assumable loans in western North Dakota
Do I have to be a veteran to assume a VA loan?
No. Any qualified buyer can assume a VA loan. You need to meet the servicer's credit and income requirements and pay a 0.5% funding fee on the assumed balance, but military service is not required.
How do I find out which listings have assumable loans?
Use ProvenAssumptions.com. It shows every listed property in our market with an assumable loan, along with the rate, balance, payment, and remaining term. That information is not available on the major consumer search portals.
How much cash do I need to assume a loan?
You need enough to cover the difference between the purchase price and the remaining loan balance, plus closing costs and the funding fee. In our market that gap commonly runs between $50,000 and $150,000, which is why the tool shows you the balance up front. You can rule a property in or out before you spend a Saturday touring it.
Are conventional loans assumable?
Generally no. Conventional mortgages carry a due on sale clause that requires payoff when the property transfers. Assumptions are almost entirely limited to VA, FHA, and USDA loans.
How long does an assumption take to close?
Typically 45 to 90 days. The servicer controls the timeline, not the local lender, so build that into your offer and your move out plan.
Does assuming a loan cost less in closing costs?
Usually yes. There is no new loan origination fee, no lender points, and in many cases no new appraisal, because you are stepping into an existing note rather than creating one.
Can I combine an assumption with a second mortgage to cover the equity gap?
Often yes, and it is how many of these deals actually close. Several local lenders will write a second lien behind an assumption for buyers with good credit. Watch the amortization term on the second, because a short one can eat the monthly advantage even when the blended rate looks attractive.
I have watched buyers in this market get priced out by rates that had nothing to do with the property they wanted. Some of them were 30 seconds of research away from a listing carrying a 2.75% note that would have put the payment squarely inside their budget. They never found it, because nobody showed it to them.
That is the entire reason this tool exists. Go look at the list before you make an offer on anything else.
