AMERICAN HERITAGE FEDERAL CREDIT UNION

On March 28, 2026, purchase adjustable-rate mortgages (ARMs) at American Heritage remain steady. The 5/1 Year ARM holds at 5.125%, unchanged over the past week and month, representing a stable yield environment with no basis point movement. Similarly, the 7/1 Year ARM remains at 5.375%, showing no change in cost of borrowing for prospective buyers.
For members considering purchase loans, this rate stability suggests predictable initial payments for ARMs, which can be advantageous for those expecting to sell or refinance within the fixed-rate period. First-time homebuyers may find these rates competitive relative to historical norms, while veterans or others seeking refinancing should assess ARM risk exposure against market forecasts.
Given current trends, members should consider their mortgage strategy carefully; if payment stability is a priority, fixed-rate options might warrant evaluation elsewhere. Conversely, stable ARM rates could benefit borrowers anticipating short- to medium-term ownership.
