Frequently Asked Questions
What is the primary difference between a Home Equity Loan and a HELOC?
A Home Equity Loan is a closed-end second mortgage disbursed as a lump sum with a fixed interest rate and fixed monthly payments. A HELOC is a revolving credit line with a variable interest rate and an initial interest-only draw period.
What is Combined Loan-to-Value (CLTV)?
CLTV is the percentage of your home's appraised value encumbered by all mortgage liens combined (1st mortgage + second mortgage). Most US lenders cap CLTV at 80% to 85%.
Is interest on home equity loans tax-deductible?
Under IRS guidelines, interest on home equity debt is only tax-deductible if the funds are used to buy, build, or substantially improve the taxpayer's home that secures the loan.
What is 'HELOC payment shock'?
Payment shock occurs after the 10-year interest-only draw window ends. The borrower can no longer withdraw funds, and monthly payments abruptly surge as principal amortization begins over the remaining 10 to 20 years.
