I told him that the less expensive supply will get booked first but then his will at a higher rate once the supply starts to deplete.

In ct- they often get tree trimmers from down south to clean up after the storms here.

Spraying wastes more material and the clean up takes longer.

My lease not includes a clause about what is not supposed to be flushed down the toilet and if the back up is a result of negligence the tenants are responsible for the service provider fees/ my time to manage the issue and the clean up if necessary.If you can get that info from the plumber who cleared the line then you may have some leverage back on the tenants 

You can hope they get their act together or start making more money in the future and clean up their credit.Rent Recovery Solutions has collected on some money for me, but its always at a discounted rate.

I also install oven liners in them to minimize the clean up when the tenants leave. 

I would make a really low offer, clean up the mess and make a traditional sale.

Loking at my invoice, I was charged 325 for tax prep and 600 for quick book clean up.  

I use Semi Gloss for for the most part however if I have to do just trims then i'll use satin.The flat paint look very dull to me and it is not easy to clean up.  

I'll take it just like it is...no cleanup necessary."
