Polish Owner refusing to sign the rent contract, Katowice; temporary address registration in Poland.

Well, I saw a flat through the olx website to rent in katowice where I am currently working. The Flat is located in Sowinskiego. I finalized the flat as I liked it and when I was about to sign the rental contract with my owner. I told him that I would be using this rental contract for my temporary address registration in Poland. Immediately he back stepped in signing the contract.

I am not sure why he was refusing to sign the contract..

The agency who was assigned from my company to take care of my work permit, Visa etc. They had to close my file successfully completing my temporary address registration in Poland.

I liked the flat so much but I cannot accept the fact he refused to sign for a simple reason. Please suggest how can I convince the owner that temporary address registration is a simple thing.

Note: My polish colleague was speaking on my behalf as the owner doesn't speak English.

He did not want to sign, as that would be evidence that he is getting a rental income from the flat. He is hiding the fact from the authorities. It would be very difficult to get you out of the flat when you have a contract.

Can I tell him that I am ready to sign that I will vacate the flat immediately after my contract expires?

But he will NOT believe you. Look for another flat.
