First ask your agent if the contract allows for the seller's funds to be used for anything other than closing costs. If it doesn't I would get a Good Faith Estimate (GFE) from your lender right away and try to renegotiate the sales price sooner rather than later.
If you can use them for other things that information will also be found in the contract. Typical items are prepaid items (items you pay for outside of closing, eg: homeowners insurance binder, appraisal, etc.) or discount points to buy down your rate. I hope that helps
"The sum of $________________________ to be used by Buyer as a contribution for the items in the paragraph above. In addition, Buyer may use the Sellerâ€™s contribution to pay for, including but not limited to, survey costs, appraisals, insurance (including flood insurance, if applicable), inspections, termite treatment and/or repair guarantee and, if Buyer is obtaining mortgage financing, escrow establishment charges, loan discount points, costs to buy down a loan, and other similar costs (unless any of the same are prohibited by Buyerâ€™s mortgage lender). Unspent sums, if any, shall remain with the Seller."
Depends on your particular contract.
Thank you for buying property this Summer!
