@Travis Winn Are you ever going to do capex(capital expenditures)? It is not included in your expenses. Example flooring 3864 sf @ $6 sf = $23184 / 8 year life span / 12 months in a year = $242 per month just for flooring. Need to budget for roof,HVAC,cabinets,appliances,etc. Vacancy of 2%. That is only 1 unit vacant for 1 month every year. $82 per month for repairs is light. 5% per month would be better. No PM and no landscaping expenses.
You're numbers are WAY off based on what Tim said. But even going with the numbers you came up with, you're only making 5% of the money you invested (down payment). IF you do have the 272K in cash, you should be expecting to make a lot more than 5%. I don't want to be an @$$, but are you kidding me?!
