I do the same thing. Just a year ago I started talking myself out of it a bit and started personalizing this home more than past homes. Still keeping resale value in mind even though I keep telling hubby I plan on being buried out back, LOL!
I buy every house with resale in mind. It's so ingrained in me after 12 houses that I can't over-personalize anything. That said, a horse property is a whole other thing, because it's already cut your prospective buyer pool down since few people will ever see the value in your killer barn or well thought out fence placement.
