For most people LLCs provide another layer of liability protection over and above their insurance policy.

.), trying to add a layer to the top, someone recommended using asphalt but I dont like that idea.If this was a 200k plus house, I would definitely replace the concrete - I am looking for suggestions on what is the best way to handle the concrete, which is the one major issue with this house, given the budget.Thanks in advance for any input!

Do a search online, but my recommendation is to use a metal Z clip or hat channel, run the opposite direction of the existing joists ( apply right over the existing ceiling and fasten to each joist as it crosses it) then install another layer of drywall. the air space and separation help with the deadening the sound transmission. if you want to try and add some blown in insulation before you do that, as @Dave Van Horn has suggested, that may help.

Its just layered with one cheap repair on top of another.

If enough people adopted the strategy it would take the value out of the layered mark-ups.

The network we have is vitally important to be able to scale and streamline the business. 

There is a personal preference side to this as well and you can layer that in qualitatively.Congrats on the success.

Being additionally insured is also an extra layer of protection for the mgmt company if the landlord/property owner makes any poor decisions.   

If you click on "Layers" then "Data" then "Parcel Data" then select the box "Owners Names" you will see owners names displayed as you scroll around on the map over properties. 

Getting anything worthwhile usually means sifting through layers of ********.
