I would not care. I would take the extra $5000.
What a buyer does with the property doesn't matter. I've given up my right to the home. Why would I expect the buyer to use it the way I would?
I don't need the person I bought this place from rolling up and asking me to change the landscaping
Again, I'm sure what you say rings true for many.
I feel the same way, but there are people out there who care about stuff like this. I know people in Newport, RI who will not sell to investors or those who will use the home for vacation properties.
