And if you did it on a trial basis, it is relatively easy to switch it back using certain systems. 

My personal privacy is not an issue for me but based on the American legal system, lawsuits being reduced to the status of a lottery, I understand why most prefer to hide.

If I had it to do over again I may go the route @Julie McCoy suggests as the up front cost for my two-piece system is (~$175 per lock and $100 for each hub) is substantial and you do have to do a little setup.

It is headquartered here, along with many other hospital systems.

I haven't seen any statistics on this, but anecdotally we're also seeing a lot of conversions to MTR, which makes a lot of sense if your property is already fully furnished and you have the systems in place for guest management. 

Additionally, find a realtor who can easily plug you in with their system and network of GCs, lenders, PMs, etc.

You have to have a system set up for vetting guests, creating leases and collecting deposits and rents.

I mentioned it to my husband today and glad we have back up keys to open the doors in case the electronic system malfunctions.

So its good to team up with good people to help you build up a good foundation so you have the best chance of success with people and systems. 

Just one of the ways our legal system can be very complex at times.
