Mohali property: RERA aur agreement ke hidden truths

Did a site visit to Godrej Alira last Saturday, looking at a 3BHK for upgrade. Currently in a 2BHK in Mohali, so evaluating if the price jump is worth it. Builder ka track record aur RERA compliance check karna bahut important lag raha hai, especially with stories about project delays. SR Homes ke bhi ek project mein interest hai, but unka agreement mein kya hidden clauses ho sakte hain? Not sure if sirf RERA website check karna enough hai. Koi experienced bande batao, title verification kaise karte hain before paying anything? Kya red flags dekhne chahiye?
