BiggerPockets and Facebook groups can also be great for networking.Feel free to reach out if you’d like help connecting with agents or investors in Illinois or Wisconsin (Have some amazing referral partners)—I’d be happy to lend a hand or share resources to get you started.

I've got a PMC referral if/when you're ready.

One thing you might think of doing is having and promoting your own website to avoid the exhorbitant fees charged by the third party sites such as Expedia, Booking.com and Air BnB.  

If you wanna be part of my team or have a referral/recommendation, I'll be more than happy to hear about it.
