Frametech:

As an art dealer we always suggest that you buy art because you like it and not for investment purposes, unless you are sure about the value of the art. Always remember that the value could go down instead of up
As a conservation framer we always suggest having at least one mat between the art and the glazing as moisture will transfer through the glazing and actually stick the art to the glass.
It's also a good idea to have the framing taken apart about every five years to clean the backside of the glazing and check for any possible damage to the art.
Also, make sure that all products that touch the art are acid free. Paper mats and cardboard are less expensive but not acid free and will eventually burn and discolor the art.
When cleaning the glazing on an existing framing use a soft cloth and preferably ammonia free foaming glass cleaner. This is especially true on Acrylic or Plexiglas, as it will scratch even using a paper towel.
Always remember the size and weight of the completed framing will dictate how it should be attached to the wall, especially mirrors, which tend to weigh much more than art; so pick your hangers accordingly.
Next time you go antique store shopping, check out the art and especially the frames. Sometimes the frame can be more valuable than the art, so keep you eyes open for those old and unique treasures.
