I’m not sure how the financing would work for such a move, being that I have 50k in student loans and 216k owed on the primary residence and work as a traveling nurse on a modest income.

Consumer spending strong, travel at record highs, price of gas low, etc.  

I have a traveling nurse ready to rent  it “as is” too as an option. 4bed 2bath with 2 additional rooms needing egress in the basement. $115k 

You can also write off travel to and from the property and more.

There are definitely pros and cons to all situations, you would just need decide what is best for you.Would listing it as a mid-term (traveling nurses, doctors, business professionals, contractors, etc) or a short term rental be an option? 

I've been in Lisbon for around 4 years - initially travelling between London and Lisbon before settling.  

I have lived in both places but if comparing price and travel time I don't know which one to decide on.

Are they an executive, an employee on 6-month business travel, etc.?

Sounds like a cool idea though...the only place I've seen them is outside the US on Travel channels and such.

I have had travel nurses, medical students, and military members stay for multiple months in some of my STRs.
