When things get weird (and something will likely happen eventually), the lease agreement is always best to refer back to.

Does any has any attorney reference in PA?

Big box stores also typically have contractors they refer out or a list somewhere.

But if you decided to do your own thing, then ask for help afterwords, they would refer you to an attorney that handles this type of problem in your area Well, that scenario is what Pace Morby, dear leader, just did!

System is $2670.For reference, I am usually all-in furnace and AC for about $5000 for a single-family home in Milwaukee.

Go to meet ups, ask for refers, Facebook is a great tool for look for recommendations too

what information or references would you need?

Are you referring to syndications or something else more specific than just acquisitions? 

In return my tenants treat me and my properties very well, stay longer and refer friends.  

Going to make this into its own post for others to reference in future!
