If you do not agree to any point in the lease then you can alter that after negotiation with the owner and this change must be written on the lease. So, this is another advice that never forget to write down all of the changes made in the lease. Besides recording all the lease changes, keep the record of the requests you ever made to the owner, the actions and the agreements against that request must also be written in your file.
Keep this file at a safe place so that to minimize the chances of being lost and so that this file can easily be used for reference in future. It is the possibility that your landlord or the owner is unaware of certain law, if you find this situation then do tell him or check the law again.
