Q: My wife has been bugging me about painting our house.

I like the color it is and the paint is in good shape. She says we need the house to be one of those modern colors to look good for re-sale. We don't plan on selling in the near future, so I don't see the point. Besides, I hate those new colors. They all look like baby food colors to me. You know, sort of mashed up spinach green, predigested squash orange, and baby oatmeal gray. Is it really important to have your house ready for resale at all times?

A: I'm guessing that you're close to my age and went through avocado green and harvest gold. It's dejavu, isn't it? I also don't personally care for the muddy colors (painting professionals call it chalky) that are so popular now, and I suspect they will become unpopular quickly. However, that's a personal prejudice rather than a professional opinion. I also believe that in the hands of really good decorators there are always good, long-lasting color choices.
As to your question, I can't think of any reason to paint a house if the paint is in good shape and you like it. I do advise people to always think of resale when they buy or remodel because everyone will sell someday. However, unless you foresee a sale in the near future, repainting now serves no purpose.
It is important to acknowledge that paint should be kept in good condition. Most modern siding is seriously damaged by water and needs good paint to protect it. Cracking paint is not just ugly; it's a major problem for your siding.
I hesitate to sound like a marriage counselor instead of a real estate broker, but it's possible that your wife is feeling that the house is just dated and she wants a change. You might look for colors together and see if there is one you can both live with. It's better to paint the house than have an unhappy mate, so you might consider painting just to keep a happy home.
