We also buy at a discount (pricing depending on those qualities). 

I found the son on Facebook and sent a quick intro giving my condolences, expressed my interest in purchasing the property, and provided my phone # in case he decides to follow up.I'm in the process of preapproval with a couple lenders, and have reached out to a couple realtors in my area to see which may be a good fit.

Nicholas, it depends on what you are buying.

great advice provided - what I will add to this is if you have smokers and its not allowed I would offer to allow them out of the lease with no penalty.

For many years I was contacted by the housing office to provide input of my rents, both Section 8 and market rented units and participated in their annual surveys. 

As a few have mentioned, the best way would be to call the listing agents directly, but depending on how much time you want to dedicate, setting and going on multiple appointments with different people could prove to be time-consuming.
