Outside, the husband, who is a friend of mine, had been getting some estimates on replacing the patio concrete & bricks / built in bbq as the patio was in disrepair.

Often this isn't a paper throwaway filter like a central A/C has, but a section of wire or plastic mesh in the front grille that you can pull out and wash.

Moved a couple walls, remodeled two bathrooms, added a third bathroom, remodeled kitchen, new windows and doors, added a window, resurfaced pool, landscaping front and back, added a back patio area, interior and exterior paint, roof repair, termite treatment, new flooring throughout, etc, and some surprises when opening up walls and floors.Sweated for a month with no offers then got 2 full price offers the same weekend.    

If they accepted your offer to fill up their little plastic can, they were most likely genuine, but many of them insisted on get the money and "filling up themselfs"

We have used plastic stretching from the eaves to the ground, with propane torpedo heaters just to get it painted.

We are all "high rollers" whom "value our time" so much that we can never be bothered to chat up the handyman in the tile isle at Home Depot or the concrete guy pouring a patio at the house down the street. 

I do have a fence up for the area that is near the outdoor patio but the property is over an acre and thru the woods so a full privacy fence enclosure would be cost and logistically prohibitive and it wouldn't stop noise, which is the main problem--even though there are acres surrounding the properties.I did ask both tenants more than once to report incidents but neither one of them wanted to deal with it and just opted to leave. 

That ceiling is silver painted plastic tiles in a drop ceiling grid instead of fibreboard, I couldn't get rid of the drop ceiling easily.

Sweet thanks, cover some plastic pipe...
