Should I go for under-construction or ready flat in Rajkot?

₹70 lakh budget hai, but Rajkot mein flat lena mushkil lag raha hai. Kids have moved out, so don't need such a big place anymore. Selling my old house. I'm looking for a compact 2BHK. Should I go for under-construction ya ready-to-move? Builders like Balaji Group ya Madhav Group ka track record kaisa hai for RTM? Kalawad Road ya Mota Mava mein options dekh raha hoon. AIIMS ke paas kuch milega?
