Another newbie here, FHA issue with underwriter

[Michael Rockefeller]

Ok so i've decided to get into the rental game and going about that by trying to land a nice low price SFH in the 20k - 30k range to start that i could live in for a year and get it paid off quickly before renting it out. I have a 640 FICO, got my down payment up to $1300 and had a guy from one of the local banks submit an FHA loan. He comes back and let's me know he can't get an underwriter for my loan. So my question is this, can i seek out an underwriter on my own? This was just last week so do i need to resubmit FHA paperwork or no?
