If your other tenants find out about it, they may feel unsafe and decide to leave and you would have to let them based on current law.As with all renters, you have to identify your risk and then mitigate it.

never know what you will see.If you decide to participate, reply on this thread with your experience.

Check with the housing office on base.If the property is negative cash flow, then you need to decide if that still makes sense.

I would think I should be mentioned with contact details for tenant to know who the property manager is, but I also wonder what if the landlord decides to remove me as property manager and appoint someone else?

If nothing else, and you decide to sell with a 1031, something to consider would be trying to time the sale towards the beginning of the calendar year so it gives you max time to potentially re-invest into something that will offset the gain, and/or strategize some additional tax savings.
