(1) No person may offer or dispose of any lot or unit in any retirement subdivision or community located in this state, nor offer or dispose in this state of any lot or unit in any retirement subdivision or community located outside this state prior to the time such subdivision or community is registered in the manner prescribed by sections 76-1301 to 76-1315;
(2) No person may dispose of any lot or unit in any retirement subdivision or community unless a current public-offering statement is delivered to the prospective purchaser and the prospective purchaser is afforded a reasonable opportunity, under no circumstances less than forty-eight hours, to examine the public-offering statement prior to the disposition;
(3) A purchaser shall have the right to cancel a contract for disposition within three business days after the date the contract is executed or within three business days after the delivery to the purchaser of the public-offering statement, whichever is later.

A developer and purchaser shall agree in writing on a specific value for each benefit received by the purchaser for purposes of this section; and
(4) If in any retirement subdivision or community a purchaser's lot or unit remains subject to any debts or liabilities of the developer or association in connection with the initial construction of the improvements to the retirement subdivision or community, the developer shall hold all payments from purchasers in escrow at a state or federally regulated financial institution located in this state until such time, not to exceed twenty-four months, that the public improvements serving the retirement subdivision or community are substantially completed and secured financing has been obtained by the developer or association (a) in an amount adequate to complete the improvements to the retirement subdivision or community as represented in the statement of record and (b) under such terms as are consistent with the budget stated in the public-offering statement.
