When an individual, like, Andrew Napolitano chooses to invest, there are many things to think about before signing any paperwork. For example, the true purpose of investing should be to save and grow money. Putting aside money for the future is a form of investment. In addition, getting a mortgage is also investing. By doing so, a family can invest in a property that will eventually be their own. Instead of renting, a person is investing in an asset. Many people struggle with the idea of mortgages and rent. Yes, renting can be much faster and less complicated, but where does that money go? By investing in a home, someone can own it and then sell it for profit down the line.
