But prefer longerVirtually any bank or CU I know requires tax returns.

Your should be getting a monthly P+L statement from your property management company and a year end statement at the end of the year.Give your accountant your bank statement where the money is deposited and the P+L from your property manager and you are all set.

I check through my bank.

Banking fees?

Banks will not use the income from the Illegal unit
