I don't know about you other real estate professionals out there, but there's something offensive to me when someone tells me they "made a killing" or are "making a killing" in real estate.
I make a nice living working with buyers and sellers in the real estate business. I endeavor to make lifelong clients, I like to make win-win situations, make people smile, make houses sell, make a good name for myself in the industry - and YES! most definitely make money. But to do those things, which I do on regular basis, I have never had to anything even remotely like make a killing. I wouldn't be very good at that.
