In relation to the initial sale or offering for sale of any condominium unit, the seller must make full disclosure of, and provide copies to the prospective buyer of, the following information relative to the condominium project:
[(4)] For developments of more than 6 units for which the notice of intent to convert is issued after the effective date of this amendatory Act of 1979, an engineer's report furnished by the developer as to the present condition of all structural components and major utility installations in the condominium, which statement shall include the approximate dates of construction, installation, major repairs and the expected useful life of such items, together with the estimated cost (in current dollars) of replacing such items; and
All of the information required by this Section which is available at the time shall be furnished to the prospective buyer before execution of the contract for sale. Thereafter, no changes or amendments may be made in any of the items furnished to the prospective buyer which would materially affect the rights of the buyer or the value of the unit without obtaining the approval of at least 75% of the buyers then owning interest in the condominium. If all of the information is not available at the time of execution of the contract for sale, then the contract shall be voidable at option of the buyer at any time up until 5 days after the last item of required information is furnished to the prospective buyer, or until the closing of the sale, whichever is earlier. Failure on the part of the seller to make full disclosure as required by this Section shall entitle the buyer to rescind the contract for sale at any time before the closing of the contract and to receive a refund of all deposit moneys paid with interest thereon at the rate then in effect for interest on judgments.
A sale is not an initial sale for the purposes of this Section if there is not a bona fide transfer of the ownership and possession of the condominium unit for the purpose of occupancy of such unit as the result of the sale or if the sale was entered into for the purpose of avoiding the requirements of this Section. The buyer in the first bona fide sale of any condominium unit has the rights granted to buyers under this Section. If the buyer in any sale of a condominium unit asserts that such sale is the first bona fide sale of that unit, the seller has the burden of proving that his interest was acquired through a bona fide sale.
