Property Management Company - Income and Expense troubles

We rent or manage properties.

How do I 1) show rent received, 2) show expenses, 3) apply that rent toward expenses, for each property?

Landlords receive a statement of rent received vs. expenses with a total due them or us. I made the property a Customer with a Job for each month of expenses. How do I show and apply rents received against the expenses balance? If I make a Job for each tenant (under the property "Customer"), then the Invoice for rents received is just marked as "Paid" when they pay their rent without applying to the Expenses.

I have tried entering Rents received as a payment against the monthly Job Expenses invoice (for the "Customer") but I don't think that will work long term. I have read the forums and tried many things unsuccessfully. I recently looked at Classes for each property but think I will have the same issue.

Any help is much appreciated!
