Congrats, having your own house is so nice! If your realtor offers home buyers insurance, you might want to get it or make it part of the deal. It covers your heating, cooling, water, (maybe even appliances, I don't recall) so if anything happens in those first few months, it's not going to come out of your pocket.

Also as first time homebuyers, you get some additional tax breaks - look up info on the web.
