Depends how serious the guy wants to stay in accommodation.
There is a rent cap of 15 % much written in the local rags how this is disregarded however there are all so those who have taken on the bandits and one.
Do a goggle on the local Newspapers and you will find the info.
Just depends if you want to jump through the hoops. A 10,000 USD payment to stay sounds like Bar Talk when the company could go and demand max 15% increase or the guy concerned could have a yarn to the rent Committee.
