I agree that the best way to make money is self manage your short term rental (not AirBNB, that is a platform).

There isn't much I can add here except for the local expertise of the Boise area and our sister company property management team get these inquires often from tenants - so we have seen many ways how not to inquire about it and a few good ways haha.

I have been following the Real Estate Investing industry for a while and just recently decided to put my focus into it and implement a plan I had in mind for years.So I went down to Puerto Vallarta I put together a team of local realtors, brokers, contractors, property managers and a lawyer. 

Quote from @Zara Massoud: Your new PM is correct and the old ones were wrong.The property manager must have your social security or tax ID number on file.

Long distance investing/managing is an obvious for me since I move every couple years, but I retire from the Navy in 5-7 years, and I'll finally settle in one place.

We manage several multi-family properties in FW. 

@Jerry Chilimidos,Here is a list of lenders who specialize in lending to IRAs and 401Ks:https://www.biggerpockets.com/member-blogs/2810/50272-list-o...I don't know where your rentals are located and how they are performing but selling might be an option vs doing cash-out refi.I would certainly consider option C.

I am also involved in management at one of the largest STR property management firms in Cashiers.

I has two GREAT property managers that immediately come to mind, one handling 5 high end high rise condos I owned in Phoenix and the other one handling a 12 unit very lower end apartment building I owned in Arlington, Texas.
