We are on all of the above, as well as:- Marriott Homes and Villas- Google Vacation Rentals- Jetblue Airlines- Allegiant Airlines- about 10+ more and soon to be American Express Travel and Hyatt's portal. 

The best advice on this topic, in my opinion, comes from 2 books:How to win friends and influence peopleNever eat aloneI am also looking for brokerages to work with or even experienced shadow / intern for to gain experience and additional knowledge.

Now, I am currently interning with a boutique developer in Boston focused on multifamily and my plan is to not only learn from them but also try and do my first deal in partnership with them.

They cannot arbitrarily make wild gambles because they feel like it - they have to operate within established risk parameters that are approved by several regulatory bodies and internal controls.

I actually interned for a company in Iowa City that did real estate, property management, new home construction and development.

Another option if you are looking to rent rooms and there are hospitals in your area is to market to travelling nurses, using a website like https://www.furnishedfinder.com/  These are shorter term leases, usually about 3 months, and you are renting to professionals who are in an area for work.

The target demographic for MTRs is traveling nurses.

It's a former adult care home, so the layout is shared bathrooms, and this would allow me to not have to change the plumbing layout while offering a competitive price-point and unique experience to travelers.

As Kevin points out, traveling nurses make good money, and their employer pays for their housing.

Traveling Mailbox is a great value.
