Invest in a house is good, the problem is the price on USA, usually we need to make an agreement with the bank to complete the payment of the house in maybe 10, 15, 20 years... a lot of things may happen in that period of time, i mean, for me 20 years is almost the half of your life paying for a house... we should invest on our knowledge to find easier way to get money and create our business, if your business is good developed, you will be able to purchase maybe 3 houses in that time that, so you will be able to receive incomes renting the place.
