You could buy a 3-4 unit multifamily property to get some experience renting it out. Do all of the property management yourself. This is best if you're targeting small-time landlords. Or if you're looking to target bigger apartment complexes, you could get a job at a property management company for a year. That will give you a good view of the administrative side. Your local community college might have a course on taking care of your home(to help with tenant turnover or knowing what your contractors need to do), or might be able to hook you up with a business mentor. Once you've spent a year or two doing something related to property management, then you can write the code and probably will already know someone who can use it.
