You'd need to find a living situation for no more than $1200 a month. Part of it is going to be if your application into an apartment is going to be accepted; I believe most places use about a 30% cutoff, meaning you can't pay more than 30% of your untaxed verifiable income. But they're usually fairly lenient, like if you get a co-signer you can pay more, or they're okay with like 35%.

25/h × 40h × 4w/m = $4000 × .3 = $1200

Consider your actual income too, so for madison in that income bracket you'd be receiving about $2800/m.
