Does notrequire proof that you were at fault.

For example, we need proof of renters insurance and proof they put electricity in their name.So, it seems odd that you are accepted but they keep wanting more information. 

Proof of concept seems to be a key part of your strategy starting off.   

If you’re In a title state make proof of utility pay off a condition of closing.

Talk to local investors, study rent comps, and understand how leasing cycles work in your chosen market.

As soon as you get the leases signed and proof of security deposit and first months rent deposited into your account your can use it.The question should be, do I even need to get the units leased out to qualify ?

The first one is the hardest but once you have a proof of concept you are off to the races :) 

Send a certified letter to the PM so you know (and have proof) it was delivered.

Provide them proof of your ability to find, fix, flip (or whatever strategy you plan to use), and then start with small amounts of their money.

Over the last several years I've been in a heavy cycle of acquiring and building rental portfolio, flipping, contracting, and being a realtor.
