Latest Answer: Buying an apartment in Coimbatore will be most beneficial to you as the real estate market is blooming there. There are many upcoming new projects that you can invest in. Though not as expensive as Tier 1 cities in India, the market value of properties in Coimbatore is still on the rise, so this is the right time for you to invest in an apartment if you want to. You need to have around at least Rs. 75 lakhs if you want to buy really posh, luxury apartments in Purva Amaiti or Purva Bluemont. But on average a 3 BHK apartment in Coimbatore would cost around Rs. 30 – 50 lakhs.
