Before even thinking about buying real estate... you need to speak with a mortgage loan officer to examine the various financing means available to you and especially what costs, interest rate and just what the monthly payments will be. Start out by checking your credit report/s and score. Truly free credit scores are available at www.CreditKarma.com - the score given is not 100% exact as far as mortgage scores go but it will be somewhat close. Stay away from scam sites like www.FreeCreditReport.com! You can take a look at your complete credit report from all 3 credit reporting agencies at www.AnnualCreditReport.com (this is the only US Government approved site) BETTER yet is to speak with a mortgage broker!
FHA? Conventional? VA? TXVET? USDA?
Either of these Mortgage Brokers will be happy to answer your questions!
