Making offers well below asking price

[Brian Midden]

I was curious how everyone goes about making offers to people that are well below asking price?

For example: If some is asking 170k for there home and after you do your due diligence you know that the most you can pay is 85k. 

Will you still make an offer of 85k? Or just move on and tell them to reach out if they become more flexible on price.

I have heard people doing both. Some say its better to move on from the deal and tell the seller to reach out if they become more flexible on the price, that way the investor doesn't get the reputation of low balling people. I also head investors say you should always make the offer because you never know.

What are everyone's thoughts?

Is getting 50% off list common in your market? Is the property really worth 50% less? Whose number here is not realistic...yours or the sellers?
