You need to be able to clean the records thoroughly and properly, either with machine or by hand. Either can work well. There is a thread here on A'gon somewhere about manual record cleaning techniques if interested.
The key for me buying used records, assuming cover is in acceptable condition, is being able to determine whether an old direty, gnarly looking record just needs a good cleaning or whether there is groove damage or surface defects like scratches that will detract from teh material and not go away with cleaning. I will say I have a pretty good eye for this from experience and seldom make mistakes buying records that are not listenable, but it is an art based on science that you can only achieve from experience.
The trick is to observe how light reflects off the records surface. The difference between groove wear or scratches and dirty records with grooves in good physical condition that a good cleaning can recover can be detected with teh naked eye with reasonable certainty based on how the light reflects from teh surface of the record.
Severely warped records are also worth staying away from. The amount of warp in a record can be estimated by looking at the record from the side from multiple angles and looking for obvious deviations from a flat plane.
Yes, and it is worth keeping some decent lined paper replacement record inner sleeves around and use these with the used records as needed for protection if current inner sleeves are dirty or severely worn or torn. You can by these for reasonable price of vendors on amazon and ebay.
