Now is the object of your partnership no matter who you will get 80,000/year rent, in one, you and your friend since it is a partnership in business, even if not open in your store, but also have to open in other stores, the rent still have to pay, which is the same as you also invested 80,000 (the first year).
Now it's time to look at the way the rent is paid, mainly depending on how you pay the law, some pay annually, some pay quarterly, if paid annually is 230,000 total investment, according to the quarterly payment is 15 + 2 = 170,000 total investment.
If the next rent is equal to the additional investment (15 + N + the total profit is how much money, plus N, and then redistribute the equity), if you do not count the additional words from the gross income to pay you 80,000 / year rent.
N=your rent rent (quarterly would be 20,000, yearly would be 80,000)
Kind of a brain fart~
