How Down Payment Percentage Is Calculated
The down payment percentage is calculated against the lesser of the purchase price or the appraised value, not the list price, the assessed value, or the borrower’s offer amount. If a borrower agrees to purchase a property for $350,000 but the appraisal returns a value of $340,000, the lender uses $340,000 as the basis for all loan calculations. A 10% down payment on $340,000 is $34,000, and the maximum loan amount is $306,000. The borrower would still owe the seller $350,000 at closing, meaning the borrower needs $34,000 (down payment) plus $10,000 (the gap between the appraised value and the contract price), plus closing costs. This gap amount is not considered part of the down payment and must be covered separately from the borrower’s own funds.
How Down Payment Affects Interest Rate and PMI
Down payment size has a direct and measurable effect on both interest rate pricing and mortgage insurance costs. On conventional loans, Fannie Mae and Freddie Mac impose loan-level price adjustments (LLPAs) based on the combination of loan-to-value (LTV) ratio and credit score. A borrower with a 95% LTV and a 700 credit score will pay a significantly higher LLPA than the same borrower at 80% LTV. These adjustments are built into the interest rate offered to the borrower, so a larger down payment results in a lower rate even before considering mortgage insurance savings. At 80% LTV (20% down), conventional PMI is eliminated entirely, and the borrower accesses the most favorable LLPA tier. For FHA loans, the mortgage insurance premium (MIP) rate is the same regardless of credit score, but borrowers who put 10% or more down are eligible for MIP cancellation after 11 years rather than paying MIP for the life of the loan .
Sourcing and Seasoning Requirements
Lenders require documentation proving the origin and stability of all down payment funds. Bank statements covering the most recent 60 days (two months) are the standard documentation requirement. Large deposits that are not part of the borrower’s regular income pattern must be explained and sourced with additional documentation, such as deposit slips, transfer confirmations, or sale agreements. Funds are considered “seasoned” when they have been in the borrower’s account for at least 60 days and do not show unusual recent activity. Cash deposits are particularly scrutinized because they cannot be traced to a specific source; borrowers who regularly deposit large amounts of cash may face additional documentation requirements or may need to provide alternative evidence of the funds’ origin.
Down Payment Assistance Programs
Many state and local housing finance agencies offer down payment assistance (DPA) programs that provide grants, forgivable loans, or low-interest second mortgages to help borrowers cover part or all of the required down payment. DPA programs are most commonly used with FHA loans and the conventional HomeReady/Home Possible programs. Eligibility requirements vary by program but typically include income limits, first-time buyer status (though many programs define “first-time” as not having owned a home in the past three years), homebuyer education course completion, and purchase within a specific geographic area. DPA funds are subject to the same documentation requirements as other down payment sources, and the lender must verify that the DPA program is an approved source under the loan program’s guidelines.
Retirement Account and Asset Liquidation for Down Payment
Borrowers may liquidate retirement accounts, investment accounts, or other assets to fund a down payment. When using retirement funds, the borrower should account for any early withdrawal penalties and income tax implications, as these reduce the net amount available for the down payment. Lenders document retirement withdrawals through the distribution statement and the corresponding bank deposit. Some retirement plans allow loans against the account balance rather than withdrawals; a 401(k) loan used for a down payment is treated as a new liability for DTI purposes, which can offset the benefit of the larger down payment. Proceeds from the sale of stocks, bonds, mutual funds, or other investment assets must be documented through brokerage statements showing the sale and the transfer of funds to the borrower’s bank account.
