It might be payment notices are going to a different address and it is simply overlooked. 

These programs offer options for less money down and in some cases DPA - Down payment assistance.As a banker for over 18+ years I am very skeptical when I hear a new name in the business only because its become tougher to lend with all of the new laws and credit/insurance requirements and regulations.  

Ability to repay - can you as the borrower afford the payments based on the loan amount.Typically they will not take into consideration the mortgage on a new property that has not been taken out as that is new.

@Marcos Carbi  If you want to allow a payment plan, Tell them this is the best I can do:Pay $xxx cash by tonight at 8pm for November's rent. and then beginning Monday Jan 20, pay $450 each Monday (in cash?

I financed this property using down payment funds from 403B and a local commercial bank.

I think it was for down payment and closing costs.

The cost associated with insurance for not having 20% is peanuts compared to what you potentially can do leveraging your down payment. 

These are features like online renter payments, tenant portal (for payments and work orders), help keeping track of work orders, tax reporting features, and accounting functionality.

When revenue is low in the first couple of year, so is the interest payment.  

Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).
