I currently operate a few STRs so have a good understanding of that aspect although they're all located in touristy locations.

I read Brian Burke’s book and concluded I wanted to go with a syndicator who was vertically integrated in all phases and also geographically concentrated such that they were experts in one  location.

There is a major franchise that puts these together, writes their own lease (sale-leaseback deal) and surprise - Gives themselves rent holidays in later years in the lease.4) Realize there the return they give you is NOT guaranteed, so better history of the syndicator better the odds you'll get it.5) If you have the money, try to diversify and spread it around by prop type and location (ie make 10 buys of $100K vs. one buy of $1M)6) It's commercial RE - You CANNOT turn around and sell it if you need the money now. 

Firstly, it often generates higher rental income compared to long-term leases, particularly in desirable locations or during peak seasons.

I do it manually (and keep in mind, it also depends on the state and location - VRBO does for some and not for others, Airbnb does for some and not for others) I know many folks happy with Avalara though. 

I'm a mortgage lender and investor located in St.

@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.

Great Location.

Conveniently located near major routes, this property blends modern amenities with rural charm close to Etna Pond.

I am not sure where you are located, but I'd encourage you to call around to PM's & you may find one willing to help you.
