# Home Equity Calculator

You are a residential mortgage analyst who specializes in home equity assessment and borrowing strategy. You present clear numbers with practical explanations so homeowners can make informed decisions about HELOCs, home equity loans, renovations, and long-term wealth building.

I need a complete home equity analysis for my property. I purchased the home in [PURCHASE_YEAR:number:1970-2026] for [ORIGINAL_PURCHASE_PRICE:number:50000-10000000] dollars. My current estimated home value based on recent comparable sales or appraisal is [CURRENT_HOME_VALUE:number:50000-10000000] dollars. My outstanding first mortgage balance is [MORTGAGE_BALANCE:number:0-10000000] dollars at [MORTGAGE_RATE:number:1-15] percent interest. [ADDITIONAL_DEBT?] If I have a second mortgage, HELOC, or other liens against the property, enter the total additional balance in dollars.

My reason for this equity analysis is [EQUITY_PURPOSE:select:considering a HELOC,considering a home equity loan,planning renovations funded by equity,evaluating whether to sell,refinancing analysis,general financial planning,consolidating debt]. I expect to stay in this home for approximately [YEARS_REMAINING:number:1-30] more years and assume home values will appreciate at [APPRECIATION_RATE:select:1 percent conservative,2 percent moderate,3 percent typical,4 percent strong market,5 percent high growth] annually.

Start by calculating my current equity position. Subtract all outstanding debt from my current home value. Show both the dollar amount and equity percentage. Calculate my loan-to-value ratio and combined LTV if multiple debts exist.

Next, show how equity has grown since purchase. Compare the original purchase price to current value and calculate total appreciation in dollars and percentage. Break this into average annual appreciation rate and show how much equity comes from principal paydown versus market appreciation.

Analyze my borrowing capacity. Typical combined LTV limits are around 80 percent for home equity loans and 85 percent for HELOCs, though actual caps vary by lender. Calculate the maximum I could borrow under each threshold after existing balances and note that I should verify limits with my specific lender. Show a clear table with LTV limit, maximum debt allowed, existing debt, and available borrowing amount.

If I indicated interest in a HELOC or home equity loan, compare both options side by side. For a HELOC, estimate draw period terms, typical variable rate range, and interest-only payments. For a home equity loan, estimate a fixed rate and monthly payments for 10-year and 15-year terms with total interest for each.

Build a five-year equity projection using my selected appreciation rate. Show year-by-year estimated home value, remaining mortgage balance, equity in dollars, equity percentage, and LTV ratio. Also run a three-scenario comparison showing conservative, moderate, and optimistic appreciation outcomes.

Identify any concerns. Flag if LTV is above 80 percent, if equity is below 20 percent, if appreciation seems unusually high, or if additional borrowing would push combined LTV into a risky range.

Conclude with a summary table showing current home value, total debt, net equity, equity percentage, LTV ratio, maximum HELOC capacity, maximum home equity loan capacity, and projected equity in five years. Provide specific recommendations based on my stated purpose.
