@Sijin Liu  Here are some ways you can reach out to more developers/investors.1) Attend (may be virtually) local real estate meetups.

General partnerships can be formed by a handshake in virtually all jurisdictions.   

Most a virtual now, so no excuse not to attend.Feel free to PM if you want to talk anything through.

And I heard about a local (virtual and in-person) meetup that I'll be attending virtually if you are interested!

A couple from out of state did a Virtual Tour of my rental apartment (NY) over the weekend.

Just went to a closing and the lawyer explained that he took the virtual closing training in RI but it really doesn't make sense because he still needs all the paper.

I guess the ideal way to look at it is: If you like the company and believe in the operator, then basically assume you are signing a document that allows you entry but which virtually negates any ability you would have to complain or sue if things went south. 

Most of our rentals are mobile homes on private property, purchased specifically because they cost ½ or less what stick-built houses of comparable square footage would have – and they bring virtually the same rent.

We also have the most meetings, pre-covid we are running around 7 a month, right now it is just the main meeting that is going virtual.

., Open Houses are prohibited, showings of tenant-occupied are prohibited, more virtual and on-line showings, and because my office is 'in the cloud' there is no need to go to an office for meetings, etc.
