It's a legal document that outlines the terms and conditions of the sale, including the purchase price, closing date, and any contingencies. However, signing this agreement can also be overwhelming, especially for first-time buyers. Here are some mistakes to avoid when signing an agreement of purchase and sale:

1. Not reviewing the document thoroughly: Before signing an agreement of purchase and sale, it's important to review the document thoroughly. Make sure you understand all the terms and conditions, including any contingencies or clauses. If you have any questions or concerns, simply ask your representing real estate agent or lawyer.
2. Not including contingencies: Contingencies are clauses in the agreement that allow you to back out of the sale if certain conditions are not met. Common contingencies include a home inspection contingency or a financing contingency. It's important to include these contingencies in the agreement to protect yourself from any unforeseen issues.
3. Not understanding the closing costs: Closing costs are expenses associated with buying a home that are due at the time of closing. These costs can include things like legal fees, title insurance, land transfer taxes, property taxes. Make sure you understand what closing costs are involved and budget for them accordingly.
4. Not obtaining everything in writing: It's important to get everything in writing when signing an agreement of purchase and sale. Verbal agreements are not legally binding, so make sure all terms and conditions are documented in the agreement.
