Anna asks: Isn't it hard to have to keep decorating with an eye towards what would be best for resale etc on each house? To not make it "your own"?
Yes and no! I might like to invest more time and money in long-term gardening projects, but don't. Every buyer we've ever had has let the gardens go completely. (And yes, I do drive by from time to time to see what plants survived!) At one house, they even mowed down a huge berm planted with bulbs and evergreens--end-of-season clearance shrubs I watered with my own sweat, digging them in August. The irony is that the whole bed required no maintenance for them!
On the other hand, my decorating style has been improved by showing our houses. After all, who doesn't have second thoughts about selling their home once it's in show-ready condition? Why not enjoy that feeling all year round? I've grown to love clutter-free living and a color scheme that flows from room to room.
