As a real estate attorney and business template specialist with over 12 years drafting and reviewing Wisconsin real estate contracts, I’ve helped hundreds of buyers, sellers, agents, and investors properly use the Wisconsin Offer to Purchase form. The official State Bar of Wisconsin WB-11 Residential Offer to Purchase is the most widely accepted and legally recognized document for buying residential property in Wisconsin. In this comprehensive guide, I’ll explain everything you need to know about the Wisconsin Offer to Purchase form, why it matters, and how to use it correctly — plus provide a free downloadable version of the current 2025-approved template.
The Wisconsin Offer to Purchase, formally known as Form WB-11 Residential Offer to Purchase, is the primary contract used to make a binding offer on 1-4 family residential property in Wisconsin. Approved by the Wisconsin Department of Safety and Professional Services (DSPS) and the Real Estate Examining Board (REEB), this standardized form replaced older versions and is mandatory for most licensed real estate agents in the state.
Unlike generic “real estate purchase agreement” templates found online, the WB-11 is specifically tailored to Wisconsin statutes (particularly Chapter 452 and Wis. Stat. § 709), Wisconsin case law, and mandatory disclosures. Using the correct Wisconsin real estate offer to purchase form protects both buyer and seller and helps avoid costly disputes.
In my experience reviewing hundreds of transactions, using a non-approved or outdated form is one of the top reasons deals fall apart or end in litigation. Wisconsin law requires that any offer submitted by a licensed broker must be on an approved form (Wis. Admin. Code REEB 16.03). Even FSBO (For Sale By Owner) transactions greatly benefit from the WB-11 because it includes:
The current 2025 version of the WB-11 is 12 pages long and contains the following major sections:
| Section | Purpose | Common Mistakes I See |
|---|---|---|
| Lines 1-30 | Property description, purchase price, earnest money | Leaving earnest money blank or too low |
| Lines 31-100 | Included/excluded items (appliances, fixtures) | Forgetting to list hot tub, security system, or EV charger |
| Financing Contingency | Buyer’s loan approval protection | Not specifying loan type (FHA/VA vs conventional) |
| Home Inspection Contingency | Right to inspect and negotiate repairs | Waiving inspection in hot market without understanding risk |
| Appraisal Contingency | Protects if property appraises low | Removing when using <10% down payment |
| Closing & Possession | Date and time of closing/occupancy | Not addressing rent-back or early possession |
| Optional Addenda | VA, FHA, secondary offers, etc. | Failing to attach required addenda |
From years of reviewing offers, here are the most critical lines buyers and agents routinely get wrong:
