I found an add for a great flat at a good price on the website of an agent in London. I visited the flat and liked it so I went to the agent's office and picked up the paperwork to fill up. I paid the holding deposit. I am now supposed to send all the application documents by August 11th (the date I am scheduled to move in).

When I returned home, I found on the internet an add on the website of another agent for exactly the same flat (same address, ground floor, I compared the pictures and it's identical) only this time it is for sale.

How do you explain this? Is this a scam? Does that mean that I will move in and a couple of months later they can ask me to move out if the flat has been sold? Should I even apply for the flat at all? I'm confused and frustrated. Please help me.
