You are getting good input.Does your lease designate how they need to pay? 

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

The main things that will distinguish Cash-out DSCR loans from each other are the pricing factors in their guidelines.1.

Design called for this to be installed on same plane as the doors.

that can be a big determining factor if something like AirBNB will or will not work (or will even be allowed by county/city)What is the layout like? 

More credit towards design center?

Zoning change and a lot of design an lobbying.
