It'll be four years this December since my gf and I purchased. I'm still amazed at how we pulled this off, given that we were two 24-year-old kids in the frickin' S.F. BAY AREA (one of, if not THE most expensive locations in the country, for those who don't know) without fancy jobs or anything. Thankfully, her parents had a nice nest egg saved up that they let us borrow from to put as a down payment. It's tough, especially once it sinks in that YOU have to fix and pay for everything, but eminently worth it.
I'll hear every now and then about someone I went to high school with, who has kids and a wife and a dog and still lives in an apartment. Makes me shudder.
