All goes according to plan my fiancé will have a real estate license by the end of October and I will start my next full time job on Oct, 8th.I am concerned about my eligibility to obtain a loan and would like to know if anybody has advice on how they would go about tweaking numbers by paying down debt and lowering the down payment to lower the Debt to income ratio to get approved or if they think I sound like I’m in a sound position.

Any time a landlord accepts rent payments in exchange for a person to live somewhere, they have created a legally binding lease.

You need an attorney's legal expertise here. 

I believe in MO there is 1 yr redemption period but there are 4 yrs that an interested party can challenge the legal process, meaning that they can not challenge the title itself but they can challenge the County for the foreclosing procedure (example, missing a proper notice etc.)

Voter-approved bonds can increase the 1% base rate, such as bonds providing funding for schools, parks, or other community services.

I want to get pre approved for my first FHA loan to acquire my first property, preferably a multi family home.

Because we knew what legal forms our court used, and I had already downloaded them on our computer, we were able to quickly serve the 3 day notices. 

I have not moved forward with any legal action at this point.

@Drew Y. it can be something as simple as a promissory note written on the back of a napkin (not that you'd ever want to do that but it is legally binding). 

Sure, depending on your local laws and your lease, you might be legally able to show it while he is gone (in Ohio we need to provide 24 hour notice), but personally, I would rather be flexible than deal with an angry tenant before move-out.
