Good for you Kim. It might be the law of attraction.. since you've worked so hard saving, researching, negotiating etc. now you're getting a better than expected rent..
I'd say good luck finding a good tenant, but don't think you need any luck ;)
You could ask the important q's you want.. then finish off with "I'm not sure if my smoke machine for rave parties will fit.." or "I'd prefer a unit with aircon for my two rottweilers to stay cool, while I'm at work" :p
