Vacant and inherited houses are still the properties fraudsters target most, because no one is checking the mail or watching the property day to day. Ask ISC or your lawyer for a title search before listing, and flag the file if it will sit vacant during the sale.
Have your lawyer set up direct notice of any changes to the title, keep the property visibly occupied or regularly checked, and never sign a document sent by email link without verifying it came from your actual lawyer's office. Legal fees for this kind of due diligence typically run $800 to $1,500.
A Torrens system makes silent title fraud harder than in some other jurisdictions, but harder is not the same as impossible, and a vacant house is exactly when the extra check is worth it. Get your hand-reviewed valuation from Joel Dyck.
