We've cleared the holidays when everyone in real estate takes some time off. No one wants to move at Christmas so many folks don't have their house on the market, waiting instead until after the New Year. In other words, now. I'm starting to see a strong uptick in seller's inspections as folks prep their house for entry into the market. Something to consider is that the first audience for your home is the other real estate agents. Once listed, they'll be touring your home so that they can be ready to refer their clients to appropriate properties.
If you have any little projects (and maybe some big ones) that you want to complete during the late winter/early spring, talk to your agent about waiting until the projects are complete before putting the house up on tour. First impressions can be critical and you don't want to jump the gun.
And, if your agent has suggested some repairs, I strongly recommend that you consider them. They know what is concerning to the buyer - they work with them daily.
