You did not mention any payment issues, have you been collecting mechanics liens with each payment installment?

When water bills come in, I pay tenants water bills to the Water and Wastewater Department directly and they reimburse me the cost owed with their next months rental installment.

The house's electrical system seems to be functioning properly, but given its age, we're wondering whether it would be beneficial to replace it entirely( I.e update the whole electrical system) My question is this: Would installing a new electrical system increase the value of the house and make it more appealing to potential buyers?

I like the tactic of paying the down payment in installments on separate dates in the future just as Pace Morby does sometimes on his deals. 

That will cost about $3000 for the utility install.  

This would be a much more affordable route, again this would depend where the home is being installed.

I depend on another department as well for answers and I too have to wait," and then asked if I would "be open to an installment of a partial payment?

I could do the installation myself, but then I have to install it just so to uninstall it again 6 months from now when she leaves.

Kitchen redo, septic system install, landscaping What was the outcome?

Install cameras to catch any dumping activities and then report to police who should issue fines, make arrests, etc.
