Of course, there are property management companies that will market the property, screen tenants, handle rent collection, and perform maintenance for you.
PMs often take 8% (+/- 2%) of the gross rent receipts for their services. In many places, that is about the same amount as the profitability of renting the place out, meaning that if I am financially able to hold the place empty, taking on the risk, time, and aggravation of finding a PM and having them rent it out doesn't leave me meaningfully better off. So, I'd rather leave it empty.
