should i buy a home or rent in my situation?
user
my recommendation is simple.  rent the fact that you have to ask the question is a clear sign that you have no business buying a home. that's not to say that it's a bad question to ask though. far more important then rather it's finically wise for you to buy a home, is the more important question of "are you emotionally ready for the responsibility and permanence" of a home.  at best, you are tying your self to the same number of rooms, same location, and same set of circumstances for the next 5-7 years. in that time it will be very unlikely that you will be able to sell the house for a profit, get your minor equity back, or even get a second loan for any reason.  you mentioned getting married soon, that means the possibility of more children, divorce, and who knows what else.  you are in an emotionally and financially turblunt time in your life. now is not the right time to buy anything large. instead rent, and focus on improving your credit rating. in 5 years time you will have a much better credit rating, get much better rates and fees, and have a much better handle on where you want to be with your home/family situation.  buying a house is not something you do on a weekend. for most people it's the culmination of years of work, searching, researching, and preparation.  often times people that buy before they are ready, will end up in foreclosure, and generally have a crappy next 15 years, as they try to work themselves out of the issue.
