As an example, for a 20 unit apartment building we would need to hit $100 profit per door per month after debt service to hit our yearly cash flow goal.After purchasing the fifth business (year 6) my business partner would retire and keep their half of the yearly profit (~$60k) and I would switch from adding new businesses to using the snowball strategy to pay down the debt on the 5 businesses.
