Why Due Diligence Can Make or Break a Purchase

Due diligence is the structured process of investigating a property before you commit to buying it. Skipping steps — or rushing through them — is one of the most expensive mistakes a buyer can make. A thorough due diligence process protects your investment, reveals hidden problems, and gives you leverage to renegotiate price or walk away if serious issues surface.

Here are the ten steps every buyer should complete, regardless of whether you're purchasing a condo, a house, or a vacant lot.

  1. Order a Title Search

    A title search verifies that the seller legally owns the property and reveals any liens, encumbrances, easements, or outstanding mortgages attached to it. Never skip this — it's a foundational step in any real estate transaction.

  2. Review Zoning and Land Use Restrictions

    Confirm what the property is legally permitted to be used for. Zoning bylaws, restrictive covenants, and heritage designations can all limit what you can do with the property.

  3. Hire a Licensed Home Inspector

    For built properties, a professional inspection reveals structural, mechanical, plumbing, and electrical issues that aren't visible to the naked eye. Always attend the inspection in person and ask questions.

  4. Review Strata/HOA Documents (if applicable)

    For condominiums or planned communities, review meeting minutes, financial statements, reserve fund studies, and bylaws. Look for pending special assessments, ongoing disputes, and signs of deferred maintenance.

  5. Verify Property Taxes and Assessments

    Request the most recent property tax statements and check for any outstanding arrears. Also look for improvement levies or local area service charges that will transfer to you as the new owner.

  6. Investigate Flood, Fire, and Environmental Risk

    Check floodplain maps, wildfire risk designations, and any known environmental contamination in the area. Environmental issues on adjacent land can sometimes affect your property's value and insurability.

  7. Confirm Survey and Boundaries

    A current survey confirms the legal boundaries of the property. It can reveal encroachments — structures built over property lines — that could become legal disputes later.

  8. Check Permits and Compliance

    Ask the seller to disclose any renovations or additions and confirm that building permits were obtained and closed. Unpermitted work can become your financial and legal responsibility after purchase.

  9. Research the Neighborhood and Development Plans

    Check local government websites for planned infrastructure, rezoning applications, or commercial development near the property. A proposed high-density development next door could significantly affect your quality of life or resale value.

  10. Secure Financing Confirmation

    Before removing subjects, have a firm mortgage commitment in writing — not just a pre-approval. Ensure the lender's appraised value supports the purchase price. If the appraisal comes in low, you may need to renegotiate.

How Long Does Due Diligence Take?

A typical subject removal period in a purchase contract is 7–14 days. This is your window to complete due diligence. In competitive markets, buyers may feel pressure to shorten this period — resist the urge. The cost of a failed due diligence item discovered after closing is almost always greater than any negotiating advantage gained by moving fast.

Work with Professionals

Due diligence is not a solo endeavor. Assemble a team: a real estate lawyer, licensed inspector, mortgage broker, and — for investment properties — a property accountant. Their expertise is worth every dollar, especially for first-time buyers.
