Apparent consideration defined to fix valuation for immovable property transfers, including sale, exchange, lease and discounted deferred payments. The definition of apparent consideration prescribes valuation for immovable property transfers: sale uses the instrument-stated consideration; exchange uses the ordinary open market price of the thing(s) exchanged or that price plus any cash component; lease uses premium and/or aggregate rent and service amounts as specified. Where consideration is payable after the transfer or agreement date, such amounts are to be treated as their discounted value as on that date.
