How to purchase Real Estate with no money?

Step 1: get/have a perfect credit score (above 850)
Step 2: Obtain a personal loan that will serve as a down payment, a gift from someone, or money out of pocket
Step 3: Find the property, and negotiate a deal for as little as possible, ideally in a home which will increase in value.
Step 3a: if you can obtain a USDA loan in your area, get one. However, if you are looking to rent the place out to make money, this type of loan will not let you do that.
Step 3b: VA loans are awesome if you have served in the military. In this case, you can rent out the house.
Step 4: Do the math on the cost of the property, and figure everything out ahead of time. If you are trying to make a profit as a landlord, then you will need to learn everything you can. It is still a LOT of work, and bad tenants can ruin everything.
Step 5: Leverage your prices. You don't have to make all the money on the property straight away, the trick is to have more coming in than what you are paying, and sometimes this just comes down to percentages. If you are successful, it is possible to get paid to borrow money. This is how venture capitalists do business.
Step 6: make your money work for you, instead of working for money. Yes this is a euphemism. This step can never truly be completed, as it is ongoing and everything up until this point has just been to reach this step. With continuous wise decisions and smart choices, you can eventually get to a point where your money is making more than you are taking from it, and at this point you are financially free.
