I went for viewing for a terrace house & few weeks later I told the agent that I intend to proceed & buy.
He said ok & a day later call me & tell me to wait for a while.

Now it's almost two weeks since then & still no update.
I texted him but he didn't offer much explanation.

What could be going on here?
I'm fine if the house is sold but I saw the ads still being run, by other agent as well.

Any possible issue with the house?
