If they are professionals, they will tell you the fees are non-negotiable, just like when you go to a professional plastic surgeon vs. a back-alley surgeon.#3 is an absolute must.

So, here's one very strong argument for never, ever EVER using accordion-type plastic or thin metal dryer vent hose. 

Same story for plumbing fixtures, not plastic. 

My 1st thought would be river rock but note that the tenants won't keep it up & it's going to be all weeds by the time you've got your next turnover.VEGAS baby  do a Vegas rock landscape zero maintance  put plastic down rock over. 

I was introduced to a wealth Plastic Surgeon in San Diego.

Both are plastic, the top I painted silver.

Put on the plastic and pay it off asap 

We went to look at it toward the middle of March 2015 and there were holes in walls, missing fixtures, odd electrical (the wiring for the back porch light and exterior outlet have been pulled into the master bedroom), tiles missing in the master shower (green plastic was duck taped across 2/3 of the surround so they could use it anyway), and cabinets missing that were not that way in November when it was listed with our Realtor.

Send the notice by regular first class mail, certified mail and have someone local post it on the door in a conspicuous place (put it up with good heavy tape & protected from rain or covered with plastic) and take a picture of it for your records. 

I have now put a plastic cover on it to stop it from getting wet but those lights need air circulation.
