i'm not sure the math adds up, anyways.

let's say you rent to a student 10 months a year and jack the price up in between. if you start at 700, and jack it up $50 a year, then after three years, you'd get

700*10 = 7000.
750*10 = 7500.
800*10 = 8000.
===============
22500

now let's say you rent to me at 700 for the whole year, and can increase by inflation:

700*12 = 8400
700*1.015*12 = 8526
700*(1.015)^2*12 = 8654
================
25580

so, you'd actually make $3000 more over those years.

10*3(700 + x) > 25500 ====> x > 150.

& that's an unreasonable expectation.

but, i'll wait until the end of august to make the case.
