| Financing Option | Best For | Key Advantages | Things to Watch |
|---|---|---|---|
| HELOC | Homeowners with equity who want flexible access | Lower rates than unsecured loans; pay as you go | Variable rates; collateral is your home |
| Home equity loan | Homeowners who want fixed monthly payments | Often fixed-rate; predictable payments | Closing costs; adds a lien on the property |
| Construction Loan | Bigger projects needing staged draws | Funds disbursed by phase; tailored to build schedule | Short-term interest-only period; requires conversion or payoff |
