There are many homes already outfitted with RV hookups, which would make adding a THOW much easier than building an ADU.

You could probably do well depending on how you furnish and outfit the place but it won't be as high as Erin's example. 

As the CEO of a turnkey outfit in Birmingham and an experienced buy-and-hold investor, I have to agree with basically all of @Jay Hinrichs' points.

your inside track on nursing and nurses could give you a major leg up on designing and outfitting rental units with those clients and customers in mind.  

I worked for an outfit with 1,000 units and the average was lower than that in the stabilized apartments.

Second, our different units over the past many months have given us some ideas of what we like (and don't like) regarding furnishings, kitchen outfitting, easy access to washer/dryer, etc.Bottom Line for us: for the monthly rate the Jacksonville, FL AirBNB hosts are currently offering, there is absolutely no way we could have lived this well in a hotel for basically the same monthly fee.

Purchase price: $5,000 Cash invested: $1 Sale price: $8,000 Blue Single family sold to an investor buddy, belong to an investment outfit in Florida What made you interested in investing in this type of deal?

The only outfit I know is Table Investments.

Step into the living and dining rooms filled with natural light and outfitted with new luxury flooring, fixtures and finishes throughout.

I may know a contractor that could help you, though I'm not sure he would be a large enough outfit depending on the size of the building/scope of work.
