I've decided that I'm not going to mention the ESA until after the application in approved. Most rental places I've seen have a policy that if your application is approved the application fee goes towards the deposits/first month rent, but if you cannot move in after being approved, as long as it is their fault (nothing available), they refund the application fee. So I may tell them about the ESA after I am approved, but before signing the lease - but signing the lease is a ways away yet, so I have time to decide how I want to do it, still.
I agree with Roxie that renting an apartment for 6 months is not a friendship, but a business deal. And if repairs are slow, that's fine - it's better than no repairs, as is the case where I live now. And a gift is the last thing I would bring to the management here. Heck, I'm planning how to go about taking them to court to get my deposits back if they refuse to give them to me (this, too, has been an issue with this complex for many, many people, yet I didn't know before I moved in). I don't know how easily I would be apprived for an apartment. I've always been on time with my rent (and paid my first 6 months in full...then got eviction notices anyway >_>), so I have a good rental history for as long as I've been renting. But to get this apartment, my dad was a security guard here, and his boss signed off on my lease without question (my dad did have to cosign for me because they don't take first-time renters without a cosigner, period). That's by biggest concern, really - since I don't know how likely it is for me to get approved anyway, I not only need to get approved, but I have no idea how to determine if it was actual discrimination or if I wouldn't have been approved anyway, regardless of the ESA.
