@Tyrone Osilesi - as @Chris Mason states, Fannie and Freddie are not the only players in town. 

On MLS, deals can be found but can be a bit more difficult to locate and can usually have more competing buyers. 

Competent legal advice may be required.

I am not at all competent at legal matters, but the fact that you had a contract and then tried to basically pull a sneaky on the wholesalers may suggest you need a little extra legal help than normal. 

If you plan on transitioning into a career agent, KW or one of the bigger players might have the best training and assistance for you to get started.Best of luck!  

Build up your side/passive income.Freedom comes at a price (competence, risk, decisiveness, focus, etc.)Sounds to me like you're on the right track now.

I competed in math competition too.Bravo boys.

This PMI will stay with you for the life of the loan, so the only way to remove this would be to refinance - another expense.Lastly, you'll be competing against other investors with 20%, 25%, 40%, all cash, etc.

Agree with the others, the contract is between the PM and current owner and the current owner is responsible for terminating.If it were me, I would reach out to the current PM (if they seem competent from what you've seen) and introduce yourself. 

I also get discouraged as I feel like there is no room for me to compete in Arizona.
