A lower payment can result from borrowing for longer and does not by itself establish lower cost. Compare both loans at the same exit month, including remaining debt. Matching the current remaining term or keeping the current payment are separate scenarios; keeping it adds principal only when the new required payment is lower.
When Does Refinancing Make Sense?
There is no universal rate-drop or break-even cutoff that makes a refinance suitable. Use current written quotes, actual costs and several exit dates. These arithmetic scenarios do not establish eligibility, tax benefits, future interest rates or a recommendation to refinance.
The Break-Even Analysis
The first cost recovery may later reverse. Sustained recovery is evaluated through both modeled loans; equality at month zero alone is not a benefit. Each payment stops at actual payoff and the last payment is limited to the remaining amount owed. Compare the selected exit value as well as the crossing month.
The Term Extension Trap
A lower payment can result from borrowing for longer and does not by itself establish lower cost. Compare both loans at the same exit month, including remaining debt. Matching the current remaining term or keeping the current payment are separate scenarios; keeping it adds principal only when the new required payment is lower.
Cash-Out vs. Rate-and-Term
Cash-out is new borrowing, not a saving or an assumed increase in property value. New debt plus closing cash must equal old payoff plus requested proceeds plus fees. The economic comparison offsets proceeds against their additional debt. Renovation returns, taxes, sale costs and loan approval are not modeled.
