| Hold & Invest the Spread |
Don't prepay the mortgage. Instead, invest the monthly savings you're getting from your below-market rate. |
Guaranteed arbitrage at risk-free rates |
| Keep as Rental |
If you're moving, rent the property instead of selling. Your cheap mortgage stays in place. |
Preserves the rate; rental income covers cheap mortgage |
| Sell with Assumption |
If FHA/VA, the buyer can assume your mortgage and inherit your low rate. |
Rate lock adds premium to sale price |
| Cash-Out Refi |
Refinance to access equity in a lump sum. Replaces your existing mortgage entirely. |
DESTROYS the rate lock — almost never worth it |
| HELOC (2nd Lien) |
Open a home equity line of credit as a second mortgage to tap equity. |
Preserves rate but HELOC rates are high |
