Use this calculator to estimate the potential loan amount and cash required for a Home Equity Conversion Mortgage (HECM) for Purchase. This type of reverse mortgage allows seniors (62+) to purchase a new home and eliminate monthly mortgage payments.

Note: This calculator provides estimates. The actual Principal Limit Factor (PLF) and loan amount depend on current market conditions, specific lender policies, and FHA guidelines at the time of application. Consult with a HECM specialist for precise figures.

var purchasePrice = parseFloat(document.getElementById("purchasePrice").value);
var borrowerAge = parseFloat(document.getElementById("borrowerAge").value);
var expectedInterestRate = parseFloat(document.getElementById("expectedInterestRate").value);

if (isNaN(purchasePrice) || isNaN(borrowerAge) || isNaN(expectedInterestRate) || isNaN(imipRate) || isNaN(fhaMaxClaim) ||
purchasePrice <= 0 || borrowerAge < 62 || expectedInterestRate <= 0 || imipRate < 0 || fhaMaxClaim <= 0) {
document.getElementById("hecmResults").innerHTML = "Please enter valid positive numbers for all fields. Borrower's age must be 62 or older.";
return;
}
// Step 1: Determine Adjusted Property Value
// For HECM for Purchase, it's the lesser of the purchase price or the FHA maximum claim amount.
var adjustedValue = Math.min(purchasePrice, fhaMaxClaim);
// Step 2: Estimate Principal Limit Factor (PLF)
// This is a simplified estimation. Actual PLF depends on complex FHA tables.
// PLF generally increases with age and decreases with the Expected Interest Rate.
// The formula below is a heuristic approximation for demonstration purposes.
var estimatedPLF = (0.008 * borrowerAge) – (0.015 * expectedInterestRate) – 0.05;
// Ensure PLF is within a reasonable range (e.g., 0.30 to 0.70)
estimatedPLF = Math.max(0.30, Math.min(0.70, estimatedPLF));
// Step 3: Calculate Gross Principal Limit
var grossPrincipalLimit = adjustedValue * estimatedPLF;
// Step 4: Calculate Initial Mortgage Insurance Premium (IMIP)
// IMIP is typically 2.0% of the Adjusted Value for HECM for Purchase.
var imipAmount = (imipRate / 100) * adjustedValue;
// Step 5: Calculate Net Principal Limit (Available Funds)
var netPrincipalLimit = grossPrincipalLimit – imipAmount;
// Ensure Net Principal Limit is not negative
netPrincipalLimit = Math.max(0, netPrincipalLimit);
// Step 6: Calculate Cash Required at Closing
var cashRequired = purchasePrice – netPrincipalLimit;
// Ensure cash required is not negative (though it should always be positive for HECM for Purchase)
cashRequired = Math.max(0, cashRequired);
// Display results

Understanding the HECM for Purchase
The Home Equity Conversion Mortgage (HECM) for Purchase is a specialized reverse mortgage program insured by the Federal Housing Administration (FHA). It allows individuals aged 62 or older to purchase a new primary residence and obtain a reverse mortgage in a single transaction. The primary benefit is the elimination of monthly mortgage payments, as long as the borrower lives in the home, pays property taxes, homeowner's insurance, and maintains the property.
How HECM for Purchase Works
Instead of making monthly mortgage payments, the borrower uses the HECM loan proceeds to cover a significant portion of the home's purchase price. The difference between the purchase price and the HECM loan amount is paid by the borrower as a cash down payment (referred to as "Cash Required at Closing" in this context). The loan balance grows over time with accrued interest and mortgage insurance premiums, but repayment is typically deferred until the last borrower leaves the home permanently.
Key Factors Influencing Your HECM Loan Amount
Home Purchase Price: The actual cost of the home you intend to buy.
Youngest Borrower's Age: This is a critical factor. The older the youngest borrower, the higher the Principal Limit Factor (PLF) and thus, the larger the potential loan amount.
Expected Interest Rate (EIR): This rate, set at loan origination, is used to calculate your Principal Limit. A lower EIR generally results in a higher Principal Limit.
Initial Mortgage Insurance Premium (IMIP) Rate: An upfront premium paid to FHA, typically 2.0% of the Adjusted Property Value for HECM for Purchase, which protects both the borrower and the lender.
FHA Maximum Claim Amount: FHA sets a maximum property value that it will insure for HECM loans. If your home's purchase price exceeds this amount, the FHA Maximum Claim Amount will be used for calculation purposes.
Understanding the Calculator Outputs
Adjusted Property Value: This is the lesser of your home's purchase price or the FHA Maximum Claim Amount. This value is used as the basis for calculating your loan.
Estimated Principal Limit Factor (PLF): A percentage determined by your age and the Expected Interest Rate. It's multiplied by the Adjusted Property Value to determine your Gross Principal Limit. This calculator provides an estimate, as actual PLFs are based on complex FHA tables.
Gross Principal Limit: The maximum amount of funds available before deducting the Initial Mortgage Insurance Premium.
Initial Mortgage Insurance Premium (IMIP): The upfront FHA insurance premium, calculated as a percentage of the Adjusted Property Value.
Net Principal Limit (Available Funds): This is your actual estimated HECM loan amount, representing the funds available to you after the IMIP is deducted from the Gross Principal Limit.
Cash Required at Closing: The amount of cash you will need to bring to closing, which is the difference between the Home Purchase Price and the Net Principal Limit. This covers the portion of the home's cost not covered by the HECM loan.
Important Considerations
While a HECM for Purchase can be an excellent tool for seniors, it's essential to understand all aspects. The loan balance grows over time, and you remain responsible for property taxes, homeowner's insurance, and home maintenance. Failure to meet these obligations can lead to foreclosure. Always consult with a HUD-approved HECM counselor and a qualified HECM lender to understand if this product is right for your specific financial situation.
