More rules for Form WB-13
Included in purchase price is the Property, all Fixtures on the Property as of the date stated on line 1 of this Offer (unless excluded at lines 17-18), and the following additional items you list. The terms of this Offer, not the listing contract or marketing materials, determine what items are included or not included. Annual crops are not part of the purchase price unless otherwise agreed.
Not included in purchase price is Seller's personal property (unless included at lines 12-13) and the following items you list. Identify Fixtures that are on the Property to be excluded by Seller or that are rented and will continue to be owned by the lessor.
Seller may keep the Property on the market and accept secondary offers after binding acceptance of this Offer.
Acceptance occurs when all Buyers and Sellers have signed one copy of the Offer, or separate but identical copies of the Offer. Deadlines in the Offer are commonly calculated from acceptance. Consider whether short term Deadlines running from acceptance provide adequate time for both binding acceptance and performance.
Wisconsin law requires owners of real property that does not include any buildings to provide Buyers with a Vacant Land Disclosure Report (lines 82, 83).
Complete the date of Seller's Vacant Land Disclosure Report, which was received by Buyer, or strike as applicable, and insert conditions not already included in the disclosure report (lines 93, 94, 95, 96, 97, 98, 99, 100, 101, 181).
If the GOVERNMENT PROGRAMS box is marked, Seller shall deliver to Buyer, within the number of days you enter (“15” if left blank) after acceptance of this Offer, a list of all federal, state, county, and local conservation, farmland, environmental, or other land use programs, agreements, restrictions, or conservation easements, which apply to any part of the Property, along with disclosure of any penalties, fees, withdrawal charges, or payback obligations pending, or currently deferred, if any (lines 181, 182, 183, 186).
Terms of this Offer that are preceded by an open box are part of this offer ONLY if the box is marked such as with an “X”. They are not part of this offer if marked “N/A” or are left blank (line 559).
This Offer is contingent upon Buyer obtaining, at Buyer's expense, the reports or documentation required by any optional provisions checked on lines 256-281 (lines 243, 244).
The optional provisions checked on lines 256-281 shall be deemed satisfied unless Buyer delivers the following within the number of days you enter (“30” if left blank) after acceptance.

This Offer is contingent upon a qualified independent inspector conducting an inspection of the Property after the date on line 1 of this Offer that discloses no Defects (lines 305, 319, 320, 321).
This contingency shall be deemed satisfied unless Buyer, within the number of days you enter (“15” if left blank) after acceptance, delivers to Seller a copy of the written inspection report(s) dated after the date on line 1 of this Offer and a written notice listing the Defect(s) identified in those report(s) to which Buyer objects (Notice of Defects).
