As a realestate builder, you can construct both residential and commercial property to make a profit for your business. You can also maximize your investment by building as many homes on the property that space will allow or by building a few multi-family units. You can sell these properties to families looking to buy a home in the residential market, companies looking to buy in the commercial market, or as spec homes to other investors in the business.
Investing as a realestate builder, rather than someone who buys homes already on the market, is a bit different because, although it may be a bit more work during the construction process, you may spend less money to finish a project and have a few more options upon selling.
