Buying your first home in Ontario involves navigating legal complexities. Key tips for first-time homebuyers include hiring a real estate lawyer early to review documents and protect your interests, understanding the Agreement of Purchase and Sale, conducting a title search, and reviewing mortgage documents. Be aware of land transfer tax and potential rebates, include home inspection clauses, and review condominium status certificates if applicable. Prepare for closing adjustments, conduct a final walkthrough, and ensure proper registration and transfer of ownership on closing day.
