What are your go-to non-Biggerpockets Youtube channels for REI? 

They must be an official partner of BP.

Apparently Hospitable uses a public API and is not a official partner with VRBO.

We have a PMS which also doubles as channel manager and is also integrated into our site. 

.: Quote from @John Underwood: I provide cable channels or you tube TV.How are you handling YoutubeTV?

Quote from @Golan Corshidi: Hey all,I used all the advice and wisdom from these channels and decided to do my first deal out of state.

My passion for real estate has been a lifelong journey, and I’m thrilled to channel that enthusiasm into helping others find their perfect home.When I’m not busy with real estate, you can find me skydive diving, hitting the gym, capturing moments through photography, or enjoying long walks and runs with my dog, Chip.

We manage about 80 so likely some of these may not be cost effective for you if you have a smaller portfolio:PMS: StreamlinePricing: RevMax (but I also recommend Beyond Pricing)Channel Manager: BookingPal (RentalsUnited is also good)Automations (Locks, Thermostats): LynxAirDNA for market dataHope that helps!

Not a new member, i've been on BP for a while now but never really did an official introduction.

They also state that they do not communicate to the channels unless you attribute a booking to the channel (there is a spot on a booking that says "Tracking - Listing Site".
