But everyone seems to offer some kind of vacation rental/Airbnb insurance product now.

Also some employers offer summer internships so its useful to list it and target those students as well. 

I own MTR's in a San Antonio medical center and I can give you this advise: Traveling nurses/professionals are looking for small accommodations (lower price point), they are concerned with safety, as they are usually women traveling alone, well-lit walkways by their parking spot, private entrances/bath/laundry.

Real Estate prices are competitive and the area offers plenty of activities, from outdoor recreation to shopping.

They are generally completed in 3-4 months and offer a much more cost efficient way to buy a nice home. 

@Dan Heuschele: Love the long game strategy with appreciation, and I think San Diego (and California, in general) offers great appreciation.

Since I was a medical student, I've always been passionate about making smart investments for my future, and real estate has piqued my interest for its potential to generate passive income and build long-term wealth.

The dealer I’m working with generally works with individuals and not so much investors, so their partners don’t really offer much for investment loans, so my next step is to explore the loan aspect further and see what I can turn up.

I wonder how many $M's of dollars the OP has invested in his own real estate empire, or is he (like most of the advice-offering "experts") offering advice with no real personal experience in the game.   

They admit that their hit rate/accuracy is low but offer zero refunds on any of their packages.
