Conventional loans backed by Fannie Mae and Freddie Mac are generally not assumable, though exceptions may be allowed for adjustable-rate mortgages.
All loans insured by the SBA require a personal guarantee from every owner with a 20 percent or greater equity stake in the business.
Only government-backed mortgages — loans backed by the Federal Housing Administration, U.S. Department of Agriculture and U.S. Department of Veterans Affairs — can qualify as assumable mortgages.
