Multi-family houses are the ideal method for new investors to get started. Numbers are the best method to show why these are excellent income properties for new investors. Assume you have two properties on the market. The first is a single-family detached home that costs $200,000. A $300,000 duplex is the other possibility. Even though the duplex isn't much bigger, it commands a $100K premium. Despite the fact that the duplex has a considerably higher mortgage payment, the fact that you will be able to fill it with two tenants rather than one makes a significant difference. You generate more money since each tenant pays a little less than they would for the complete single-family home.
