Great question, Jarrod! I know someone in Vincennes who can help you. Also, a trusted realtor in the Vincennes area will be able to recommend a good mortgage broker/lender. First-time home buyers can receive a tax credit (up $8,000 from $7500). If you shoot me an email, I'll get you that local realtor for you.
So, begin with the realtor and ask for some recommended mortgage professionals. Once you find the best lender/broker for you, they will tell you your range. Begin your home search, schedule showings, and you'll be unpacking those boxes before you know it!
