Consider hiring a property management company. Especially if you will not be living on the property (but even if you are), it can make a world of difference to let the pros handle day-to-day needs. A good property management company can get your units rented and handle advertisements, maintenance, rent collection and more.Build a team of go-to pros. Speaking of pros, it is important to build up a team of people who will be there to help when you need them. A lawyer, tax adviser, plumber, electrician and handyperson would be a good start.
