I always replace them for my rentals and also always install new ball type shut off valves.Good luck with your current projects.

I install the GE dishwashers that run 300 at home depot.

In the next couple of months my time will be opening up greatly and I'll be able to do just about anything (driving for dollars, installing ceiling fans, replacing garage door openers, painting walls, whatever) in exchange for and education and, eventually, a cut of the deals. 

@Jake PickettMany OOS investors set themselves up for failure because they don't truly take the time to understand:1) The Class of the NEIGHBORHOOD they are buying in - which is relative to the overall area.2) The Class of the PROPERTY they are buying - which is relative to the overall area.3) The Class of the TENANT POOL the Neighborhood & Property will attract - which is relative to the overall area.4) The Class of the CONTRACTORS that will work on their Property, given the Neighborhood location - which is relative to the overall area.5) The Class of the PROPERTY MANAGEMENT COMPANIES (PMC) that will manage their Property, given the Neighborhood location and the Tenants it will attract - which is relative to the overall area.6) That a Class X NEIGHBORHOOD will have mostly Class X PROPERTIES, which will only attract Class X TENANTS, CONTRACTORS AND PMCs and deliver Class X RESULTS.7) That OOS property Class rankings are often different than the Class ranking of the local market they live.8) Class A is relatively easy to manage, can even be DIY remote managed from another state.

Someone just posted a FB post about this same thing- He literally wants to lock the thermostats or install a digital one so he can keep from from setting it below 68 becuase "There is no valid reason for any one to set it below that temp ever"This is the kind of thing that makes people assume landlords only care about money and not humans. 

A friend of mine in Dallas is having solar installed and his projected savings over the next 25 years is over $75,000.  

It does look like the new one is a hair higher than the old one in the installed picture there.

I shortened a window by, after framing for the right height, simply having the installer make a flashing fascia from the bottom of the actual window down to the sill.

The labor alone to manufacture your own flooring, who knows, I guess it depends on how good you are and if you have all the equipment and time.I just installed a oak solid wood prefinished floor for $2.25 a sq foot.I feel time is better spent looking for a closeout, or looking on craigs list until you find what you want.

I have a friends father that does work on the side and installed a top of the line buderous boiler in my house for a price you would not believe.
