When NOT to Refinance

Situation Why
Moving within 2-3 years Won’t recoup closing costs
Small rate drop (<0.5%) Savings too small to justify costs
Recent rate lock at pandemic low (2.5-3.5%) Extremely unlikely to beat that rate again
Extended loan term with little rate improvement Restarting 30-year clock costs more long-term
Underwater on mortgage Can’t refinance with negative equity (some exceptions)
Credit score dropped significantly May not qualify for a better rate
Planning to pay off soon Closing costs wasted
High closing costs in your state Break-even takes too long

Refinance Decision Matrix

Rate Drop Time in Home Recommendation
2%+ Any duration Definitely refinance
1-2% 3+ years Probably refinance
0.75-1% 4+ years Consider it (run the numbers)
0.5-0.75% 5+ years Maybe (only if low closing costs)
Less than 0.5% Any Skip it (not worth the hassle)

Types of Refinance

Type What It Does Best For
Rate-and-term Lower rate and/or change term Most refinancers
Cash-out Tap equity for cash Renovations, debt consolidation
Cash-in Pay down balance at closing Remove PMI or qualify for better rate
Streamline (FHA/VA) Simplified refi for existing FHA/VA loans FHA/VA borrowers (less paperwork, lower costs)
No-closing-cost Lender covers costs for slightly higher rate Short time horizon, limited cash

No-Closing-Cost Refinance: The Trade-Off

Option Rate Monthly Payment ($300K) Upfront Cost 5-Year Total 10-Year Total
Standard refi 6.00% $1,799 $9,000 $116,940 $224,880
No-cost refi 6.35% $1,867 $0 $112,020 $224,040
Difference +0.35% +$68/mo -$9,000 -$4,920 +$840

No-closing-cost wins if you stay less than ~8 years. Standard refi wins for longer holds.
