LOL. Accounting problem! Use an accountant & quickbooks. Like I always say, it's good that most believe in stocks and shy away from income properties. Otherwise there would be oversaturation of landlords . Truth be told, a decent residential rental gives a 11-13% return on investment which keeps growing.
these %s sound right on, there are some opportunies right now for 30-40% year over year by paying cash let me say this isn't for everyone usually , usually involves a quick lowend rehabb bought from a bank, hassle to manage though, in my area there are hedge funds, buying 100 at a time, shrug
