Start with the company servicing the seller’s current mortgage and ask for its assumption department. Your loan officer can help compare the options, but an advertised assumable rate is not permission to transfer the loan. Confirm the loan type, approval process and actual terms before building an offer around it.
The question behind the listing
An open-house question came through our team: a listing advertised an assumable loan, and the loan officer wanted to know whether he could handle it or needed the existing lender. This article comes from that question. Identifying details are omitted, and the email does not establish that an assumption was approved or completed.
Ask the current servicer first
The original lender and today’s servicer may be different companies. Use the seller’s current mortgage statement to identify the starting point. Request the assumption application, document checklist, applicable fees and processing estimate. Ask who actually reviews and approves the transfer. A formal assumption involves the creditor’s written agreement to accept a new borrower on an existing mortgage.

A low rate does not answer the cash question
Ask for the current unpaid loan balance as well as the rate and remaining term. The purchase price can be much higher than the balance being assumed. That difference needs a funding plan, and closing costs still need to be counted. For illustration only, a $600,000 purchase with a $400,000 assumed balance leaves a $200,000 difference before closing costs and adjustments. Those are hypothetical numbers, not figures from the email.
Compare the whole transaction
If covering that difference requires another loan, ask the assumption team whether that financing is allowed before counting on it. Compare total cash needed, both payments, fees and the proposed timeline against a new mortgage. Have your agent coordinate contract deadlines with the servicer’s written requirements. Avoid promising a closing date from the advertised rate alone.
Give the seller a clear exit
For a VA loan, ask specifically about release of liability and the seller’s entitlement. They are separate issues. A seller can be released from liability while entitlement remains tied to the loan unless an eligible buyer substitutes entitlement. Confirm the actual treatment with the servicer rather than assuming the sale resolves both.

Bring the statement and the listing
The useful next conversation starts with the listing, the current loan statement, the sale price and the buyer’s available funds. I can help organize that comparison and identify the questions for the assumption team. Then the decision can rest on the full transaction, not just one appealing number.
