Property Size for Mid-Term in Tucson

[Thomas Nordberg]

I am looking at purchasing several properties to set up as Mid-term rentals in Tucson, ideally around the Hospitals in town to focus on traveling healthcare professionals. I have received conflicting advice on property size, with the options being 

1: finding apartments / sub 1000 sq ft 1/2 BR homes 

2: "Traditional" 3/2 or 3/3 size homes

3: Most Bedrooms / Bathrooms possible

My goal is to focus on renting these out via Furnished Finder and Air BnB

For those of you who have experience in this area, or for those of you who have worked in a field requiring mid term stays, what are your recommendations and thoughts?

Thanks in advance!

Tom
