When you compare parking options, isn't the comparison of a carport (multi), vs a garage, less attractive to the potential tenant...and more expensive to fix...since you need to repair/replace all the carports that are attached at the same time (roof for example) at a higher cost per sq ft (metal vs asphalt/fiberglass)?

Otherwise it will probably not be worth my time to replace the missing window screens.http://www.homedepot.com/p/New-York-Wire-15-in-x-37-in-Fiberglass-Adjustable-Screen-FSP8559-U/203176387

I attempted to repair it with a fiberglass repair kit, but it reopened.

@Art Maydan, I second the recommendation for blown-in (cellulose or fiberglass).

(Green board is fine under solid surface walls, from fiberglass to acrylic to whatever else, and is usually preferred, but don't do it under tile.)

If much of the basic basement finishing happened way back when, you probably have, behind the walls, plastic sheeting stretched across the concrete block walls, fiberglass batts stuffed into the rim joist cavities, organic fiberboard insulation lining the plastic, and regular drywall with untreated 2x2's serving as studs, nailed into the concrete masonry block walls with a powder-actuated nailer.

A couple of days ago a car smashed a portion of the fence, and yesterday we discovered a fiberglass shower pan is cracked so we've got completely redo the shower.

A big one-piece fiberglass enclosure?

I'd be a lot more worried about exposure to chopped fiberglass or vermiculite than mouse poo.

My tenant informed me that she slipped, fell and caused a big crack in the fiberglass tub with the knee.
