Let the seller keep the park owned homes?

I have been looking at a bunch of parks in the southeast and park owned homes are the norm rather than the exception. As a result, I have run into seller after seller with unrealistic expectations regarding the value of these homes. With that said, has anybody offered to let the seller keep the park owned homes as a concession in the negotiation process? My logic is as follows; 1) they would be held by a separate entity, 2) the seller would benefit from rents and/or payments, 3) this would offset the purported value in arriving at a purchase price, 4) if the seller was not interested, it would negate his argument regarding the value of the assets. While I have reviewed the MHP forum, I have not seen anything on this topic and would appreciate any/all input. Thank you in advance.
