I kept the addendum I used and just added a couple sentences that made tenant comfortable while still protecting me.

If there is a defect during the sale process (which is common), the court will protect everyone else before the buyer. 

When you feel like you have acquired enough assets that you feel like you need more protection. 

As a former social worker, I am becoming very aware that as landlords and property managers we are becoming the first line of defense to protect vulnerable tenants.

Also ask about an LLC, which has some more legal protections.

I wanna protect myself from liability because all properties will be bough cash so I don’t want to lose any of them.But my question is what LLC structure should I use?

A friend of mine had an idea to buy "smaller cell sites" since the larger towers seem to be out of our price range as well as dominated by larger players.

However, not sure how’d you handle protecting the seller’s interest in getting paid as you’d have to refi / cash out refi to get rid of her mortgage and pay her whatever she is due, realtor fees, etc (or whatever fees aren’t taken care of at the subject to closing).

You should be aware that you cannot rely on this answer to provide you with any protection against tax penalties.

If they are causing property damage, they are violating the lease and are not protected by the "nonpayment" freeze.
