I'm not saying your lying but 3 weeks seriously? I know for a fact housing officers need to first get end of lease contractors out to remove all old carpet, furniture etc... then re-do any gas, plumbing and electrical work to meet current legislations, then any additional contractor work such as plastering, painting and renovating one room (preferably a kitchen). I don't think all this can be done in 3 weeks given the time scale and paper work involved.
However if you are telling the truth, then so be it.
