Should I look for a home with an assumable mortgage?

Seeking out a home with an assumable mortgage makes sense mainly when the existing loan's rate is meaningfully below what a buyer would get on a new mortgage today, since that gap is where the real savings live. It should not be the only factor in choosing a home, since the buyer still needs to qualify with the current lender and cover the difference between the loan balance and the purchase price. Assumable loans are also uncommon enough that narrowing a search to only those listings can shrink the pool significantly.
