You’re right to flag these since a lot of the terms lean in the buyer’s favour, so it’s good you’re checking now.

1. Payment Timing:
21 days for the Balance Deposit is long. Asking for 14 is fair. The automatic 1-month extension should be conditional, not automatic. And 8% interest is low, pushing for 10% makes sense. Also, if you delay documents, buyer’s timeline should pause with interest, not for free.

2. Vendor Default:
Double deposit is standard but harsh. You can ask for deposit + RM10K instead. Add a clause for delays beyond your control, like bank or title issues, so you don’t get penalized unfairly.

3. Buyer Default & Refunds:
Only losing the deposit is soft. Suggest a 10% penalty on the full price if they back out. Also, 14 days to refund if transfer fails is tight, 30 days gives you breathing room for paperwork or bank delays.
