Truly, how hard can this be?

I swear. I don't understand how hard buying a house can be! I think it is mostly our fault because we are being VERY specific about the area and type of house we buy---but come on people! We are also thinking about renting a place incase we do decide to build a house on a piece of property we might buy. I doubt it though. After building this little house on my parents property--Darren and I are DONE with building. We have put an offer in on 5 houses now, and not one of them has worked out for one reason or another. I HATE THIS. I know there is a lesson in all of this, but right now I just want to complain and cry like a baby. Sorry.
