How this calculator works
Equity is the home value minus what you still owe. The most a lender will usually let you borrow is the value times its combined loan-to-value limit, minus your mortgage balance; many lenders stop at 80-85%. The monthly payment amortizes the amount you draw over the repayment term at the rate you enter. Lending limits and rates are set by the lender, not the state.

Median home value and borrowing ceiling by state
An 80% combined loan-to-value ceiling on each state's median-valued home caps the total of your mortgage and the HELOC at the amount shown; subtract what you owe to see your room. Yearly property tax is the state effective rate on that value.

Frequently Asked Questions
How much home equity can I borrow?
Multiply your home value by the lender's combined loan-to-value limit and subtract your mortgage balance. On a $400,000 home with $240,000 owed and an 80% limit, that is $320,000 minus $240,000, or $80,000.
Is HELOC interest tax deductible?
For federal income tax, interest is deductible only when the money buys, builds or substantially improves the home that secures the loan, within the mortgage-debt limits. States that tax income mostly start from federal income, but check your state's rules before counting on a deduction.
