Thinking About New Houses

I have been fighting it, but I am getting the urge to house hunt. I own my condo, but I have always known I want something bigger. I have been fighting the urge, because I can't afford a down payment right now or a mortgage payment. So I don't even want to think yet about mortgage quotes. I don't know how people can afford a mortgage. My condo mortgage was so low, it was doable then. I still have too many bills is the problem, and I would have a hard time adding a mortgage payment. I guess people who buy homes don't have bills like me. Or maybe they do and that is how the whole mortgage mess happened! So I may look at new houses, but it will only be window shopping!
