The mold exposure can make you ill for the rest of your life, so go with that. Also go with your missus has asthma and therefore the place is unlivable.

You need a doctor letter to the management saying that you have had emergency treatment for severe allergic reaction, are unable to live in your present environment, and must leave as soon as you are able to find another place to live because your health is being affected. If you have a family doctor he should write it for you, ask him if he can write it for multiple chemical sensitivities, or MCS once you have that you can pretty much walk away the same day with all your money back.
