Thanks for your input.
My brother owns a leasing company and he says that most people that list with him, do so because they are move/relocated for work related projects.
His biggest problem is finding quality subcontractors. He says that it used to be tracking (administrative) all the information, but there are all these cheap programs aimed at fixing that now.
Hope that helps.
He says it has been pretty easy to get good tenants, but it's getting harder. The market used to be hard to buy, but is getting easier = less good tenants.
The thing that pisses off landlords the most is problem tenants. The ones that don't pay and/or damage the property. In tenant-friendly states, the eviction process can be long, complicated, expensive and riddled with pitfalls. Additionally, there are "professional tenants" out there who try to game the system by legally squatting.
