Try facebook if you want the virtual thing but some will meet in person through meetup.com or even post here on the Bigger Pockets Marketplace.  

I see you might be pretty far away so visiting an REI group might be difficult but there are plenty of facebook pages for investors in the Philly area.  

I’ll shoot you a DM as well so we can connect.My cleaners are pretty slammed as of now but you can find some cleaners on TurnoverBnB and use that to sync with listing calendar and cleaner calendars, and I would try an arvada Facebook Airbnb group or reach out to listings closest to you and see if they will share cleaners.

Some post on meetup.com and some are even on facebook. 

You can also check meetup.com or search facebook for real estate investment groups, clubs, or meetings in your area.

you need to stand out from the crowd, unlike LTRs, which can work as cookie cutter properties, do lots of research and join a strong group, Facebook groups have great info

And facebook groups are going to be key.

If not, I find a lot of great local businesses through the Nextdoor app, or local community Facebook groups.

Facebook marketplace is huge for rentals
