Know the cap. Lenders limit how much a seller can contribute. Conventional loans on a primary or second home: 3% of price above 90% loan-to-value, 6% from 75.01–90%, 9% at 75% or less; 2% on investment property. Contributions can't fund your down payment, and excess must be deducted from the sales price.
Payment math is principal and interest only, for illustration; not a loan quote or commitment to lend. Concession limits: Fannie Mae Selling Guide B3-4.1-02. FHA, VA and USDA have their own limits. Confirm with your lender.
