Home Shopping Network

So everyone seems to be buying houses right now! Amber and I are looking into buying a house in Warrensburg, while she's searching for a job some where around Lee's Summit (KC). I realize (like with everything in life) that I'm pretty clueless of finaces and such. Outside having a job as a cook in HS for spending $$, I never had to deal with moneys. Luckily, Amber has helped her mom as long as she can remember, so that helps. All this home buying mumbo jumbo is beyond me though: equity, 80/20, PMI, mortgage... Ok, so I know the basics of some of it but I don't know it well enough to be able to haggle and stuff. Oh well another learning experience
