Plus the toolkit: the go/no-go scorecard, offer-condition clauses in plain language, the document-demand list, the site-cost worksheet, the questions to ask the municipality, health unit and conservation authority, how to read the free Ontario Well Records map, who to hire and in what order, and a plain-English glossary.

What you get that the free pages do not give you

1. The fast fit test. One question you answer standing on the lot: can a house, a driveway, a septic bed and a replacement bed all fit at the same time without cheating any of them? If not, you do not have a buildable plan. You have hope, and hope is not an approval.
2. The go/no-go scorecard. One printed page, filled in on site. Any “no” you cannot fix or price is a reason to renegotiate or walk.
3. The offer conditions, in plain language. What to make the deal conditional on, and the documents to demand from the seller before your conditions run out.
4. The site-cost worksheet. Septic, well, hydro run, driveway, clearing, grading and fees on one sheet, so the land price and the real price sit next to each other.
5. The questions to ask, and who to ask. The municipality, the health unit and the conservation authority each hold a piece of the answer. The book tells you which piece, and what to ask so you get it in writing.

Who it is for, and who should skip it

It is for anyone in Ontario looking at a vacant lot, rural or in town, who wants to know what the lot will really cost before the conditions in the offer run out. It is most useful before you make the offer, and still useful during the conditional period.

Skip it if the lot is already yours and the house is designed, or if it is a serviced lot in a subdivision where the builder handles the site. The free “Is this lot buildable?” checklist and the lot-buying guide cover the basics at no cost.
