MPAC
MPAC: a practical Canadian real estate investor guide to definition, deal math, underwriting use, common traps, and Realist.ca implementation.
Definition
MPAC is Ontario’s Municipal Property Assessment Corporation, which assesses properties for municipal tax purposes.
Example
In underwriting, tag MPAC beside the exact source input and rerun the model when that input changes. The point is not a pretty metric; it is a better buy, hold, refinance, or walk decision.
Why It Matters
MPAC can change after-tax proceeds, legal risk, carrying cost, and closing certainty. Ignoring it can turn a good spreadsheet into a bad real deal.
Investor Interpretation
Use it to kill bad deals quickly. If the back-of-envelope version does not survive conservative assumptions, do not spend five hours making it look alive.
Realist Tie-In
Realist.ca can make MPAC searchable as an encyclopedia entry, link it to property underwriting, and show it beside listings, saved analyses, market pages, and investor lead magnets.
