If switches and outlets are getting up there and Im doing fixtures and its a long term hold I replace them.

Example, new light fixtures and new sink faucets, vanities, and toilets.

I installed 3 power failure light fixtures where the old smokes had been. 

However they have units that sit vacant longer. and tend to have more problems from the tenants they do have.Just like I do from my one unit that has just average fixtures, faucets, layout and paint schemes.I am happy to ereport back thank you to all the original respondents to the original thread.

 $21k for systems work, $8k for interior/exterior paint, ~$5k for the roof,  $5k fixtures, .... hard to even guess trim, floors, framing, sheetrock, tile, cabinets/counters, etc.    

Or old plumbing lines and fixtures that fail in the middle of the night?  

I'm talking busted windows, missing doors (int and ext), no plumbing fixtures, decks half tore out, siding missing, holes in the siding, cabinet doors missing, whole cabinets missing, garbage piles, missing floors, wire stripped out...

You could try a suction cup mount like this:http://www.amazon.com/Panavise-809-Camera-Window-Suction-Cup/dp/B000246ST6Numerous other choices, depending on the size of your camera.Keep in mind an HD video camera is only 2 megapixels where most point and shoots are 8-12 MP and pro DSLR cameras are in the 16-18 MP range.

Also, after reading several posts regarding wood decking (everything from treated pine to ipe), my conclusions are unless you're going to adhere to a strict and consistent maintenance program, any wood will eventually turn into a bland gray board, with cupping, splitting, and splintering as a possible added bonus.

Just look for missing hot water tanks, stripped copper, or missing fixtures.
