Most likely the GST. As for the changes from BLR to BR, no one really knows the rate yet, most likely it will be similar to what we are getting now anyway.

Well.. when GST in implemented, surely there will be inflation!

However, the economy going down or not, I cannot speculate. It may seem like the case and people would like to hedge their investments by buying gold and other precious metals, or bond unit trusts funds. When the rental market is down, you may find it difficult to hold onto your properties too. So they may think it would be better to let it go and wait until the storm passes.
