If you have a compass or phone-compass reading of your main door's exact facing (0–359.9°), enter it for a much more precise 24-mountain analysis. Measure standing inside facing out, away from metal, and average a few readings. Leave blank to use the 8-direction above.

Only structural work, roof, main-door re-orientation, or major wall demolition counts — not paint, flooring, or furniture. Major renovation resets the property's period and affects the whole analysis.
