It's incredible to me how often we have difficulties simply getting in to see homes that are available for sale. It's not uncommon for 1 out of every 4 properties we try to set up showing appointment on are unavailable for one reason or another. Excuses range from difficult renters in a property to visiting family to minor repairs being undertaken. If you want to get your house sold, make it available for showings. That means you may have to inconvenience yourselves or put in some extra effort to get it ready on short notice.
Despite the national media building up the housing market, it's still difficult to find the right buyer for any property. If you have your property listed for sale, jump through whatever hoops you have to in order to accommodate showings. If you don't, the otherwise perfect buyer may simply write off your home because they don't feel you're serious about the sale.
Make this easier by always keeping your home in show condition. Be willing to take the dog for a walk on short notice so you can get out of the way when an agent calls with last minute buyers. Treat buyers and their agents as if they're customers and you'll be a lot closer to actually getting your home sold.
