A true wholesale deal shouldn't be priced at "retail". You will continually come across people that think their property is worth a lot more than it is, especially today. When you offer them a wholesale price they may get upset but it's a numbers game and you are running a business. If they are truly motivated and understand you are not going to pay retail they will usually come down. I always ask what is the lowest price you would take right now. They always come down from what they originally wanted just from that one questions alone. As far as offending people sadly that is going to happen on occasion mainly because they don't know or don't want to accept the current value of the property. You have to have some thick skin in this business. You'll get hung up on, laughed at, have doors shut in your face etc... but at the end of the day as long as you've researched thoroughly and know your numbers it will work out.
