When buying foreclosed, condition of property is the most important factor. Typically when buying foreclosed, the property is a fraction of retail value and therefore profit can be instantly made. Profits are generally 30%-60% of total value sold.
If you are buying a foreclosed property it is good to understand the surrounding areas and how future economic scenarios will affect your investment. Guarding this investment is key when aiming for high profits.

How do you fund this type of venture? Right now there is tons of grant money for people that want to start buying and selling houses. You can also check out low interest rate loans by creditors who are struggling for customers! Right now is the best time to start ANYTHING.
Start doing research by looking at what an investment near you would cost and go from there. I would start with whatever money you can afford to loose, don't throw the whole pig at one venture.
