If you're looking at residential real estate I'd definitely recommend attending the regular Bigger Pockets meetup the 2nd Wednesday of every month.

I have an offer from a client to lend me 400k for a cash purchase in Denver’s crazy market.

There's tons of great info in these: https://www.biggerpockets.com/podcastStart building your network by finding and attending meet-ups in your area: https://www.biggerpockets.com/eventsDefinitely check out @Justin Brown 's meet-up.

If you can make the timing work, attend a local meet-up (assuming it doesn't get canceled...).

I think in about 30 days they will be back to business as usual as far as having the staff to start attending to new loans  

I currently live in Cleveland and was hoping to network with other real estate investors in the area, I would love to attend real estate investment groups suggested.

Attend the FREE WEBINARS       3.

This has consisted of tons of webinars, reading books and articles, attending meetings and joining my local REIA.

There's pretty much nothing worse than taking a "deal" to an investor only to have them point out what a crappy deal it is - topped with the fact that the wholesaler probably has a pretty juicy assignment fee on there.I would be sure to attend a bunch of local REI meetups and get to know others in attendance. 

You should attend!
