Short answer: yes. In Texas, sellers often pay part or all of a buyer's closing costs. Each loan program caps how much.
Your Realtor writes the seller contribution into the offer. In a slower market, sellers are often more open to it than to a big price cut.
A seller can also use that money to buy down your interest rate. Sometimes that lowers your monthly payment more than a small price reduction would, for a similar cost to the seller. It depends on the numbers, so ask your loan officer to run both side by side for the home.
