OREGON - When you're looking to make money in the Portland real estate market, it's important to look at the recent trends. One of the major trends is the migration of homeowners from the city to the suburbs. This is good news for Portland real estate investors, but it also means that vacancies in the city are increasing. As a result, investors are turning to long-term rental properties. As a result, the housing market is now catering more to rehabbers and landlords than to flippers.
