Your tenants are not unique to this situation and honestly, I think they would appreciate you looking out for them :) As for the common areas, yes, they should be cleaned more often.

We have kind of a unique building in our area.

Also you don't need an LLC to be covered, you can purchase under your name and just have an umbrella policy.Now yes you can go the construction loan route, hell the VA has a loan like that but that is up to 4 units. ( You may want to explore that as well) And other investing types would be with other investors, private money, and hard money.  

@Michael JackmanI've been doing some napkin math exploring the possibilities.

My kid isn't allowed to live in the house that I am paying rent for is a hard pill to swallow.I am just chalking it up to the unique situation I we are in as a nation.  

If the cracks in the foundation are what is driving the move then you need to get that explored before doing anything.

You all gave very unique answers with a lot of good information, and I appreciate the time you took to respond to this post and help me out 

Too many OPs have the answer they want to hear or they want to hear their problem is unique and unsolvable so they don’t have to do anything. 

I’d love to talk more about my company and the unique management climate here in Philadelphia.

I will definitely keep that in mind and will let you know if we explore that area.
