Does the Junk Yard next door hurt the property, how much?

[Vincent Somma]

Okay okay, so yes there is a not so bad 3 bed 4 bath house in what you would call a very nice area, great school, low crime, for 50k. The major downside (besides a few repairs) is that it is right next to a junk yard, with like 50 cars in the back lot. The property has a high fence, but how much impact will the junk yard have on 1. renting the property, 2.flipping and selling the property?

Thank you all

Side note, If a bank buys a property for 3,000, and is trying to sell if for 50k, has anyone had good luck getting a bargain in this situatuion? or do they tend to be extrememly firm with their number. Granted i realize this is a generalization, i am just looking for anyones past experiences. Thanks again.
