It is designed for properties that need work but can be used on rent ready properties as well. 

You'll first need to hire an architect to design the unit.

No one is going to care that 3 people are in a bedroom "designed for 2 people".

Speak to the contractor's in-house architect and ask them what they need to see in the geo tech report in order to feel confident designing the house there.

Rethinking the design, the basement would likely also only have two bedrooms (perhaps each with their own bath for a higher rent) in order to accommodate the utilities.

I am an architect who uses generative design to streamline the production of mid-size projects but I am not a full-on programmer.

It is the policy design that matters.

Home office deduction is available if you have a rental property and designated space exclusively used for rental property business.

They also help with operations as you can run them with one bank account and one set of books (if you manage the books properly by designating funds to each property).

Full disclosure - that is not what we have used, but it seems to get the job done.We did take the time to consult a designer on furnishings and got professional pictures, which seems obvious until you look at your competition, and our unit has booked within a week of listing both times that it has been available.
