Short answer：A provisional sale agreement can be legally binding and is not a free reservation. Confirm the property, parties, payments, dates, possession and special conditions before signing.
Complete essential terms
Identify included roofs, parking or other interests, deposit recipient, contract and completion dates and possession terms. Do not sign material blanks assuming they can later be freely changed.
Resolve open risks
Seek advice on financing, title, alterations and repairs and whether conditions are needed. Failure to complete can have consequences beyond the deposit, depending on the contract and circumstances.
Before deciding
- Check current title and sale authority
- Read default and agency-fee terms
- Keep copies of signed documents
