My questions below are the thoughts I'm trying to figure out at this time:What have you been doing to either protect or expand your portfolio during this moment of uncertainty?

And even if you evicted them and got a judgment against them, 401k’s are protected assets.

and asked them to consider landlord/owner protections for 12 months beyond the passing of the bill.I have also asked my mortgage companies to move my mortgages to interest only for the duration of the MA declaration of emergency plus 2 months. 

PUTTING out this fire of Covid19 requires us to massive focus on making test kids, masks, PPE (personal protective equipment), ventilators and the like to PUT out the fire.   

I recommend sending both tenants an email asking them to refrain from having others to the property until the order of stay is lifted for the protection of all tenants.

You should understand it completely, and it should protect both you and the other party. 

It's a little more complex, but all of the appreciated value would be tax protected.

If its in a LLC already what legal forms should I have to protect the investors and myself? 

Also I read somewhere that having no mortgage (properties paid for in cash) protects you against this type of theft , is that true ?

Once you figure out the real estate tax game and how to protect yourself there, you will make a lot of money here.
