1st Home purchase

[Trevon Peracca]

Good afternoon all! 

I am in search for advice/ an investing mentor. 

I am currently serving active duty in the United States Marine Corps, and have been relocated to Chicago. 

My wife and I are trying to find and close on a house before mid October; my question is what should I do know when applying for my mortgage loan and what questions should I be asking to the agency.. I have currently been pre qualified through Veterans United home loans for 250,000.

 I understand the process of obtaining a loan and buying the home, but I do not want to be blindsided by something I do not yet know about. 

Also, if there's anybody out there that is familiar with the Chicago real estate market I would love to meet with you to kind of get an idea of what I'm getting into.
