Any inputs or suggestions?

The square footage of the building can dictate whether or not additional residential rental units can be present.

@Austin Wood If I inherit a tenant, I refund the whole deposit unless I know they did additional damages after I took ownership.

I love this option, because you can leverage low down payment, get benefits of real estate, learn a lot of valuable RE skills, and can maximize your income with a furnished rental.As a SFH, you could potentially rent out rooms or an additional space out as MTR/STR, but there is potentially less privacy.

Additionally, how to use the paperwork to close the deals is unclear to me, and the author Tingle does not support his course.

I don't suggest rushing the contractor to throw out a number for you.

I would highly suggest bring a profesional with you, when you visit the property to inspect the fan.

I would suggest you head over to the short term rentals sub forum on here.

@Keenan Branch this is a great question but I would suggest treating this like any vendor for your market. 

My lawyer's team suggest that the former tenant may be too poor to pay.
