Shady deals in Bangalore

Hi,

I was looking to buy a resale flat in a popular upmarket under construction community in Whitefield. Most of the owners are refusing to sell without a cash component.

The broker is telling I will never be able to buy in resale in a full white transaction. I don't want to get into these shady deals.

Is this the norm across Bangalore ? Is my only option is to buy directly from builders? I had to consider resale as the configuration I wanted was sold out with the builder.
