Buying with low offers

[Todd Hendricks]

Hi all,

One of the keys of effective negotiation is to have some way to justify a really low (or high) offer. To get a really good discount on a property, what are some of the tactics you guys use to shave 5, 10, 20k off of the asking price? The condition of the property is a good starting point, but wanted to see what tools other folks use. 

Thanks!
