There is a scenario which takes some getting your head around that allows this sort of thing to happen. It goes something like this:
Most people who have bought property in Turkey will be aware that the tapu office must inform a purchaser if there are any debts lodged against the property. There is no way they could not tell the buyer this, it is very much part of the process and their responsibility to do so.
So, how could the owner of the building company possibly sell a property, take full payment and have a tapu issued in the new owner's name(s) without them (the purchasers) being made aware that there is a debt attached to the property they are about to take ownership of, and the debtor is the builder himself. It's impossible, surely.
But no. It's quite possible. Clever too.
You remember that bit when the builder explains that they will take power of attorney from you so you don't need to fly over to sign this and that. What a helpful thing that is.
So the builder (your power of attorney) goes to the tapu office to sign the property tapu into your name. The guy at the deeds office does what he is obliged to do and points out to him that there is a debt lodged against the property. Builder says "Yes I know" and because the deeds man has done his job and highlighted the issue, the transfer can now take place. It does, but of course the debt is still there, it transfers ownership too.
So when the builder (your PoA) says "Yes I know", sometimes he's saying "Yes I know, it was me who borrowed the money you are mentioning".
It took me a couple of years to work out fully how they did it. I'm sure it took them a couple of seconds.
