All it takes is a thief posing as a tenant to see the house is vacant and where the pipes are.After the first, and hopefully last time that happened, we installed an alarm system and if either of them are vacant again, we'll board up most windows and the back door and install an alarm.

You definitely don't need to install granite countertops for Section 8 rentals.

Very easy to install and cheaper than copper, probably higher than PVC, but this stuff will not burst in cold weather.

The look pretty easy to hook up and install.

@Vinh Huynh you can also buy a cheap dish washer install it of you don't already have it and raise rent 50$ a month I'm sure there is similar strategies I'd love to hear some

I work as a apprentice flooring installer for 7 years by the best of the best.

As a hardwood flooring installer and sander, I'm no stranger to being around the scene of development groups and residential areas around Denver and areas of Colorado. 

That still leaves plenty for me to do, including ripping out carpet and tossing out tenant-left trash, buying all materials, changing light fixtures, changing blinds, installing fans, and a dozen other small tasks that it takes to get an apartment move-in ready.Besides renovating the interior of apartments, we’ve also spent considerable sums on HVAC and windows.

Of course, the tile and sheetrock were ripped out, vapor barrier, backer board installed, new tile properly laid and grouted. 

You can also buy insulated, double pane glass and install it yourself...I recently had broken double-pane window break and ordered a new pane from fabglass.
