To qualify for a loan, focus on having a credit score of at least 620 (or 580 for FHA loans), keeping your total monthly debt under 43% of your income, and saving enough for a down payment and closing costs—about 5-10% of the home's price in total.

I know you said $5,400 but is that the correct monthly rent(total)?

Total rent s/b minimum $2,250 but with housing vouches, $2,550

You can simply request a separate check for the $100 increase to bring the total deposit in line with the new rent amount.

DSCR is going to be your best bet here.

-Max LTARV is typically 75% -Is a 12-24 Month Interest-only loan with a balloon payment - Minimum credit score is typically 600 -Interest on the Rehab is usually paid per the total drawn amount. 

My bet is you do not get sued.  

Good luck, you are a busy man with school, family and baseball.Likely your best bet is house hacking (if your partner and child are willing to share housing). 

The Note/Mortgage for each loan states the dollar amount invested & the % of the total loan by name, for each investor. 

The investor then gets the property for a few percentage points of the total property value.
