I anticipate on getting a FHA loan to secure financing. 

These people tend to be a bit more responsible, typically have a job, at least a partial security deposit, and actually care about their credit score.Regarding the specifics you ask for, you'll have to check with your local authority on their processes & procedures.

I just want to secure my future with more than a standard 9-5 pay check to paycheck kind of job and have multiple incomes instead of 1, like them..

You should have also gotten the tenant's security deposit. 

Because I have spotty job history (Mainly internships since leaving the military), securing a loan to own a property is out of the question.

personally I would pay off my home first. that would still leave you plenty to invest. it would provide more security because your home is free and clear. 

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

Over the past 3 weeks.I have someone willing to finance my 1st deal with 100k but I haven't secured the funds.

If one or more investors just pays money and expects to get a profit based on others' efforts, you have created a security and SEC laws apply.

@Mel Hayes need to sign a promissory note $45000 secured by the property and record it.
