What this is (and the name might differ in some states) is a demand from the buyer to the seller to either address a variety of defects or offer a credit to the buyer (i.e., reduce the sales price).

If the sample(s) that tested over the threshold were from under a window (which is the norm), you probably need to address the window frame/sill and I'd recommend just cutting to the chase and painting them. 

I added the new address to google maps and it was accepted.

@Michael Ebeling how does the lease address these issues?

With just an address its tough to say. 

General rule of thumb is look for properties with Cleveland in the address, anything outside of that will have POS.Start looking for contractors sooner than later - they'll make or break the whole deal. 

FYI, over the years, we've also learned to save a lot of money wasted on excessive management labor costs (we call them "stupid trips") by planning the occasional weekend to drive down, inspect our units and address any labor-cost intensive items that we can do over a 3-day weekend. 

I'm even hesitant to give you the web address I'm about to give you, because if you haven't looked for it and found it already before coming to the Bigger Pockets forums to ask strangers for help, you're way, way behind the eight ball.

@David ChanceYour concern about tax ramifications is impossible to address without knowing your numbers and your specific situation.

If you reverse look up the address sometimes the residents names show up.Can’t you just serve the paperwork to “unknown occupants”?
