In negotiating property sales, price valuation often becomes a stumbling block to deal making. But there are a number of interesting alternatives to a straight sale that allow transactions to close that otherwise might not have. Consider using deal-making tools such operating leases, land leases, percentage clauses, purchase money mortgages and third-party financing to overcome a valuation gap. Another consideration is what a seller is to do with the after-tax proceeds. Though many people consider a cash sale to be of most interest to a seller, that is not always the case.
