Years ago -- many years ago -- I was 19, newly married and renting. My (then) husband and I decided we should buy a home and went to view a few homes on our own. This was mid-70's and "Buyer Agency" really wasn't in the forefront. It was non-existent.
We toured a townhome which we liked and the listing agent approached both of us.
When he found out that we were interested, he wanted us to offer MORE then the list price by $5,000 and then he would kick-back that amount, in cash, after the deal closed.
His motivation was that he wanted to UP THE COMPS for the newly built sub-division . . . he even told us that. It was worth it to him to get the price on the units higher. He was the listing agent for the developer and it would, certainly, make the builder/developer more money with higher SOLD comps.
Now THAT was a bribe!
In the mid-70's $5,000 was a lot of money (about $15,000 in today's value.)
We didn't go for it. Although young and naive I didn't like the sounds of it. We didn't buy the new townhouse. My "ex" didn't seem to have any problems with it, but I said NO! We divorced a few years later, which is neither here nor there, but he was a jerk.
