Julio, I would like to back up what was already stated. Purchasing an aircraft in leasing it to a flight school is a bad idea. Most if not all flight school aircraft and abused. Legally the owner/operator is responsible so in the case of a lease back the operator of flight school is responsible. However if an accident happens you may find yourself in civil court for any loss.
I work with a lot of homebuilders that build aircraft. Let me say you are not allowed to lease it to a flight school for flight training. The rule is in FAR 21.191(g). You can read all about experimental aircraft on my web site

You may want to look into the Light-Sport aircraft for what you are describing this may work better for you. On my web site there is information about them.
I would also suggest purchasing a CE-172 or similar model for your own enjoyment, but remember it cost $2,000 and up for expenses every year to maintain.
