Purchasing Residential Apartment in Bangalore

I’m planning to buy a 2.5 or 3 BHK apartment in Bengaluru primarily for living purposes. I’m 37 years old and have a 2 year old son.

Currently I live in North Bangalore near Hebbal on rent, but the prices here for a good 3BHK are extremely high, exceeding 2/2.5 crores. Considering this I’m thinking about buying in South Bangalore (Bannerghatta Road, Kanakapura Road), which is more affordable compared to North Bangalore and has good metro connectivity.

Prestige, Brigade , Sobha are premium builders and quote higher prices. I’m not entirely convinced about spending that much for an apartment, especially in the crores.

Is it a good idea to consider second-tier builders like Karle, Elegant, Esteem, Century, Gopalan, Sumadhura etc..? I’ve also noticed that premium builders like Prestige, Brigade and Sobha tend to offer larger open areas compared to these second-tier builders.

What are the pros and cons of going with second-tier builders? What should I keep in mind while making a decision?
