I personally invest as a member in a passive real estate investing club, where we all go in on these together to invest small amounts, and vet new deals together every month.

Personally, I perceive a fair amount of risk in the market.  

I was wondering if I should set up another personal bank account for all activities.

A few things to keep in mind: the entire operation must be outsourced, and neither you nor your immediate family members can't be involved as you are considered "disqualified persons."

I am looking to borrow 50k from equity in a 4 unit investment property to use as a downpayment on a personal residence. 

I also know that in many cases the llc will protect my personal assets and I fully believe this is either analysis paralysis or just fear of failure.Thoughts on how to get past this and where you recommend starting?

I would be happy to refer you to the right person if you are interested, just let me know!

I'm personal friends with the owner and they do a great job. https://www.livindy.co/ 

Personally, we're okay with properties that cashflow decently, but have long term appreciation upside too.

i want to keep the group small. not like industry scale crowdfunding.if I can find a property which has okay cashflow (which is hard anyways). and can collect around 10/20 people who wants to invest some cash each.I build a company to own the property and give each person a share. and give yearly dividend to each, until sold.
