Many companies are moving to Texas for the tax benefits, because Texas is centrally located in the country,  low cost of living, technology etc.

Technology has changed the way the real estate industry functions which remove a lot of the requirements of a broker.One of the largest reasons broker's were needed for managing rental properties came from the fact that rent payments were all made in person and most management companies were using trust accounts for receiving payments.

This leads me to believe that due to productivity, coordination, technology, and increases in knowledge that the 10 yr yield will continue to stay low.

How difficult is it? 

My experience: often this "offer" is made when a tenant is having difficulty coming up with rent, either short term or on a chronic basis.

Is there a high level of difficulty to where I would need to hire someone?  

An out-of-country investment in this class would be suuuuuper high risk, especially for a beginner.Anyway, the difficulty of investing away from home is a topic that comes up constantly here at BP.

What is the level of difficulty?

Instead, I should try to improve the property slowly ultimately with the goal of doing a refi and paying them off.I have found difficulty finding 20% COC deals on larger units, I have seen 20% on duplexes.
