What the calculators are really telling you
Affordability
A lender may approve more than a household wants to carry. Compare the payment with savings, repairs, commuting, childcare, and the budget you need to keep breathing room.
Refinancing
A lower rate is useful only when the monthly savings and time in the home justify the closing costs and any term reset.
