I wouldn’t say investing in crypto is necessarily the best, but I think putting up to 5% in net worth is worth it for the upside it could generate. 

This will be a generational MF opportunity, akin to 2008 SFR.

At Bigger Pockets, I am hoping to make connections, learn, and generate wealth for myself.

This could be laborious as a one at a time deal.Not sure if this would work but you might be able to pay someone from Fivr to write a script that would do it automatically for you and generate a list based off of the multifamily addresses that you already have.   

I own a 6BR short-term rental in Estes Park, Colorado, which generates a lot of laundry—especially because we use high-quality linens.

You are right about the risk that comes with the holding period but in my opinion sometimes you have to take the risk and make sure the profit that you generate is higher than the costs that you paid by holding the deal for a specific amount of time.

Let me add some new wisdom to this.Try not to see social media as "just another channel to try my luck".It is not a separate thing, especially doing SEO or paying for ads.When it comes to lead generation, it is not (just) about generating that lead.

Name one product that completely eliminates lead generation costs, and efforts, where the leads chase you instead of you chasing them?

I've read about Benjamin Graham and Warren Buffets approach to investing at large and it resonates with me more so than the crypto-generation. 

We have a software called EZCare which our cleaners will take post clean pics and it generates a report.
