I was looking to link up with some real estate savvy individuals and came across bigger pockets.

I'm not up to date with any Massachusetts laws, but I would also vet the tenant in the next day or so and see if they are even an individual I would want to keep at the property.

The Tenant-In-Common entities are each named on the deed, as well as the Tenant-In-Common entities percentage of individual ownership.

On a personal note, we plan to invest in a self storage fund and a MF fund in 2022, and perhaps one individual deal. - investing in other asset classes outside of real estate - I know some people put all of their investment into real estate, but I am a believer in diversification, so that your entire investment portfolio isn't at risk during any downturns. - keeping some cash reserves - downturns mean opportunities for smart investorsInvesting carries risk, as does not investing.

Unfortunately well meaning parents enable the behavior.

The concern could be that you are attempting to coerce them to accept your family over another family or individual who may or may not be in a protected class.

They both would be $1,000 a month but I have seen individuals stray away just on how its advertised.

Maybe meet with each of them individually, tell them to call you if there is any funny business and you appreciate them watching out for the neighborhood, but you'd appreciate it if they do not approach the guests. 

I hear a lot about storage units, but I feel at some point individuals will think, how much "stuff" do they really need?   

Lots of investors find banks and lenders as necessary evils to acheive their individual goals, so if they make a suggestion about a lender, then the lender is usually a really good one.
