my rental contract (1+1) is about to reach its first (fixed) year. It is a bit uncommon since the second year is optional on both sides, i.e. the landlady can terminate the contract in the coming year too. While I'm generally happy with my place, I want to amend the agreement such that a) the fixed period is set to one year again (I don't want to risk having to search for a new place while I'm busy with my thesis) and b) the rent is lowered (I signed the contract just before the Lehman took the real estate prices down).
While I hope that my landlady will agree on that, I'm not sure what I need to do - can I just set up a document with my suggestions and have her sign it, or do I need to get a whole new contract and have it stamped? I don't mind the 200HK$ stamp duty but I would like to avoid the hassle.
