If I were in your position, I would either - Ask for the nurses contract or recruiter contact to verify employment and use this as the background and credit check (most travel assignments require you to get a background check prior to going to a hospital, and the contract would prove employment and term) - Offer the nurse a month to month rental with options to extend but require my cleaner to go in every month to clean and assess"

What is your experience / track record with this type and size of investment? 

We are sandwiched between well known hot spots and its an ideal location for someone who wants to explore the beach life or any of the down-town areas nearby (Los Angeles, Long Beach, Redondo, Manhattan, Southbay Etc), new build with modern amenities, washer/dryer in unit, full sized fridge, dishwasher, professional range cooktop, queen bedroom, full standing shower, large kitchen, full sized couch in the living room, private front patio. 

I have a size-able portfolio that is a mix of commercial and residential.

I like the pontoon boat rental idea as an add-on service for your STR - on decent-sized lakes, pontoon boat rentals can easily bring in $200-250 for a half day rental or $400-500 for a full day rental, so you could make a tidy little profit off of this kind of add-on amenity. 

@Ryan KleinTo attain a $3000 monthly cash flow objective in five years, begin with home hacking, then employ financing choices like as refinancing, DSCR loans, and BRRRR techniques.

@Raj MukherjeeYou are right in your analysis, Huntsville definitely has better schools and the employer profile is much better as well. 

Self-employment tax will be required on the net gain, which will of course be 0 after property expenses and depreciation.

If it has gone up and down rapidly, then that indicates a boom/bust market (typical in areas without a diverse job market such as areas where all of the jobs are in tech, energy, manufacturing, a single employer or supporting those workers for example). 

The town I am in is rather small 35,000 but has a good sized college.
