Another problem I encountered when purchasing a property in the US is that I didn't have employment record, W-2, social security number, credit score, etc.

If they have never lived in that area before than they are probably in sticker shock.

What I've encountered, if you enter into an Agreement of Sale prior to 90 days FHA requires 2 Appraisals; conventional does not have this requirement in my area, but requires more down payment.

They cut signs in half and take half, leaving one of their stickers on the remaining half.Call them "haters", "low lifes", and "bullies" if you want but you're the one putting up illegal signs.

This was Monday last week and I've still haven't received anything.I've had a few encounters with these types of agents.

You will encounter business costs.

He will encounter the same issues with anyone else that is interested in the property.

I have encountered quite a few listings/sellers in the current market who seem to be unrealistic about the value of their property.

The only reason I want to develop a relationship with an agent is to request further information when I do encounter a property I like. 

We all get in the line of fire from time to time.I have not encountered this situations.
