I can completely understand packing you twin toddlers for any reason it's not easy. But the chances of an Agent buying your house is very unlikely. However, if you can buy another before selling yours that would be the best thing to do. But if you can't, just let your Agent know that you will need 24hrs notice before showing and that you want only pre qualified buyers so you only get buyers not just "thinkers". I know with small children we don't have time to do the deep cleaning but be sure your house is clean, clean, clean! That means base boards dust free and back yard toys organized. It makes a big difference to a buyer. You want to make your house show the best so it will sell faster in this down market. I wish you the Best!
