Rent and Buy!
You can rent and later buy properties, only depending on cash-flow. Then even rent out places you are not using, but you loose the right to save-game if it is rented out. You have to have a business bank account to have the funds deposited without you having to collect in person. If you have no business bank account, then you have to call to collect money weekly on a Friday. If you miss Friday rent collection (before 8pm), via a cut scene, they tell you that a fellow called and collected the cash, showed proof of your ID and took the rent. (You've lost it)!
This is a harp back to one of the early missions, of things that happened to you when you first landed and got rolled for your wallet and passport. That's why you have had some difficulty and had to do some of the things you've done.
