Pune first-time buyers: What tricky builder-buyer agreement clauses did you find?

My lease ends in 3 months and I'm finally done with renting. Looking at projects in Baner and Hinjewadi, like Kohinoor Famville, made me really check legal documents. Many builder-buyer agreements have tricky clauses that totally favor them, especially for delays or material changes. It's not just about RERA registration, right? Understanding the actual contract before signing is crucial. What red flag clauses have you seen in Pune? If a builder like EH Reality Llp delays, is RERA effective for getting real compensation, or is it mostly on paper? Hope this helps other first-time buyers.
