One of the biggest advantages of this home is the partial assumable FHA loan at 2.875%. With approximately $260,000 remaining, the current payment is about $1,075 per month compared to roughly $1,559 at today’s 6% rates — a savings of nearly $500 per month or about $5,800 per year. In today’s interest-rate environment, opportunities like this are extremely rare. You can change a house, but you can’t change a locked-in interest rate like this.
