There are several strategies used in real estate to generate a profit but only 1 strategy will create wealth.
Wholesaling is a strategy that will create " CASH NOW" and you can wholesale without ever using any of your own money or credit. However wholesaling will never create wealth but will generate a nice profit for today. Truth is you will need to keep on wholesaling to keep on getting paid.
Flipping properties or BUY, FIX AND FLIP is also a " CASH NOW" strategy. You will have to use your own money or private money to purchase and rehab properties. Though this strategy will generate a nice profit if done right it will never create long term wealth.You will need to keep on flipping to keep making money.
