You have three main options that don't require replacing your existing mortgage: a HELOC (revolving credit line), a home equity loan (lump-sum second mortgage), or a home equity sharing agreement (no monthly payments; the investor takes a share of future appreciation instead). Each suits a different need and risk profile.
Refinancing your entire mortgage to extract equity makes sense only when it also improves your rate. When your current mortgage rate is lower than today's rates, replacing it to access equity is expensive. The CFPB covers the two most common alternatives — home equity loans and HELOCs — both of which sit as second liens behind your existing mortgage, leaving your first-mortgage rate untouched.
A HELOC gives you a revolving credit line — you draw what you need, when you need it, and pay interest only on the outstanding balance. During the draw period (commonly 10 years), you can borrow, repay, and re-borrow. The rate is typically variable, pegged to the prime rate. Best for: ongoing or uncertain expenses like a multi-phase renovation or tuition paid semester by semester.
A home equity loan disburses a single lump sum at a fixed rate with fixed monthly payments over 5–30 years. You know exactly what you owe every month from day one. Best for: a defined, one-time need — a specific renovation project, debt consolidation, or a down payment on a second property. The trade-off versus a HELOC: you pay interest on the full amount from day one, whether or not you've spent it all.
A newer product: a company gives you a lump sum today in exchange for a percentage of your home's future appreciation (and sometimes a portion of its current value). There are no monthly payments — settlement happens when you sell or refinance, typically within 10–30 years. This suits homeowners who are equity-rich but cash-flow constrained. The cost can be high if your home appreciates significantly, and terms vary widely, so read any agreement carefully.
