Switzerland does impose some restrictions on foreign and non-residents buying property but you can still buy and several members of my family actually own property there.

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

Just made $800,000 profit south of you in Floresville and La Vernia in commercial property.  

3) Buy a few out of state properties directly through an agent and work with a property manager to manage them? 

Also make sure you are comfortable with some holding costs if the units don't get rented right away (if vacant).Also look into if there is rent control in the area that the property is located.

The 1031 must be a sale of investment property followed by the purchase of investment property. 

Can they prove how long it takes to rent a vacant property?

@Travis Boyd, 19 of my MTRs are in multifamily properties.

What is your average rent amount for all properties managed?

Providing relocation assistance to tenants, for example, if I want to sell the property or move back in - this can range from one month's rent to thousands of dollars (e.g tenant has a disability, minor children, elderly it will cost you more), depending on the city.
