I recently purchased a four-plex on August 29th.?

On Sept. 1st, I signed a contract with a property management company. The contract states I will be paid my share of the rent on the tenth of each month. The property management company charges 8% to manage the property. Today, I called and asked when I would be paid and was told that I wouldn't be paid until October 10th. I believe I should have been paid on the tenth of September.

My reasoning is that rent is always pre-paid. I have always pre-paid my rent in every apartment I have lived in.

Who do you believe is correct? The property management company or me?

Thank you for your input.
