Thank you for your question. The answer depends on the offer made. In making an offer on a property a Buyer will actually fill out a SC contract to Buy and Sell Real Estate. In that contract the Buyer will fill out a section that gives the Seller a deadline to respond to the offer, otherwise the contract expires. The typical timeframe is anywhere from that same day, to 5 days, depending on the situation. If you'd like more information on how you should address this deadline please feel free to call or email me. I'm a Realtor with Carolina One Real Estate located in Mount Pleasant. Have a great day!
