Homeowners with paid-off houses can take out home equity loans by meeting lender requirements like credit score, income, and loan-to-value ratio, typically up to 85% of home value. Pros include lower interest rates, fixed payments, and tax-deductible interest if used for home improvements. Cons involve foreclosure risk, closing costs, less flexible terms, and potential higher costs than other loans. Alternatives include cash-out refinance, HELOCs, and reverse mortgages.
