She herself is now in a nursing home and will not be living in the house.  

without having much demand from nurses, how this MTR business is doing for investors? 

I would not recommend doing this with travel nurses as they are already background checked.

How frequently do other travel nurse unit operators send out a cleaning crew?

I think the less risky is a long term, but there are plenty of travel nurses that come through who would gladly do a short term (furnished, so something to consider) and won't wreck your place.

For example, travel nurses and digital nomads are typically looking for very different property types than a family relocating to an area.

Traveling nurses?

Hi all, I have 2 nurses staying at my place, they initially signed a lease for 2months.

You could live in an amazing city, there are big hospitals around if you wanted to go for nurses. 2 units can be upgraded immediately (delivered vacant) and rented out so you could "add value".

I just helped a travel nurse that was denied by five other lenders due to the seasonality of their job and lenders concern with occupancy fraud.
