You have an option to allow tenants to pay rent with a credit card?!? I am shocked about two things. First, doesn't it hurt you to lose the processing fee off the top? Second, why on earth are tenants still paying with a check when they could pay with a credit card and reap insane rewards points. Getting airline miles for such a large, regular expenditure is a free flight per year (not to mention charging and paying off rent each month probably would help increase your credit limit and credit score).
