Commercial Real Estate Investing Commercial real estate investing is a good place to start because it would be relatively safe compared to other styles of investing your hard-earned money. The downside of commercial real estate is the idea that in most cases you need large sums of money to get started. Many real estate investors don't even consider this option until they've built a large portfolio and also have tons of money to risk. Let's say you purchased a large office building and rented it to potential businesses. Your income stream should be relatively stable because most organizations and/or businesses that rent from you will need to stay long-term (generally the minimum commercial lease is 3 to 5 years). Most businesses, whether it's an accountant or a doctor, prefer to stay in the same place for as long as possible, due to the constant flow of customers. So, in a perfect world, it would provide you with a stable stream of income. House overturning
