I know you are probably a little frazzled because of all the stress you are under now, and I really do hope things turn out well for you. Maybe you could work with the new landlord to see if you could move in earlier..
One thing that surprised me was that whenever we have met in mudcat before you have vehement attacked perceived prejudices. In this e-mail you condemn your new landlord as greedy and evil and your old landlord as a spoiled brat. I'm sure the new place is high-priced, but if it is over-priced you should look elsewhere instead of condemning someone for charging for services, yes landlords charge money...so do teachers. The old landlord may be inexperienced (and I think you should teach him a valuable lesson) but to say he is a spoiled brat with a "typical" response to a single woman is just silly. If he were really spoiled, he wouldn't work at the construction firm and he would have had dad's company fix the house instead of doing it himself. And I'm really interested to hear what "typical" response all 20 year old boys have to single women...did he buy you a drink and ask you on a date?
It would be better to work with these people than to fight with them, but if it comes down to it, get legal help.
