You can control rent but cannot control appreciation.

I know without hard evidence I can't make conclusions or accusations to tenant B, and at the end of the day can't control what individuals do, but is there anything I could do to maybe address or deter the issue?

One or two from time to time might fly in through an open door but a big infestation shouldn't be present in my opinion even though they are considered helpful when they are outside controlling other pests.I'd want to call the exterminator and pay the bill directly instead of having the tenant do it but I like the thought of the tenant paying.

The proposed ADU ordinance working its way through City Planning would prohibit ADU between the curb and the primary residence (unless being added to an lawfully existing garage).If you rent out the front house and it was built before 1978 it may come under rent control (something to verify).

No issues so far, we did end up getting the electronic controls, kind of wish we didn't but we'll see what happens in the future.

All the while, you always have control and nobody else, not even your attorney, can manage or sell your property except for you.If you need to prove ownership for financing or any other reason, you simple produce your company documents as well as your banking and accounting records.

Hello all, The wife and I will be stationed in San Antonio Texas for another 3 years on a controlled tour.

No weekends, No holidays, better pay, and I have some control of my schedule. 

Probably a better idea would be a remote thermostat that you can control with your phone. 

If you're in Oakland, you just lost your rent control exemption for owner-occupied duplexes...I run a team in the Bay Area and another in the Raleigh metro and we're right in the middle of working with a number of our Bay Area investors on exchanging out of their local properties and into multiple places in the Triangle ... we're increasing their cash flow and putting them in position for more capital growth (when using conservative estimates).Unless you're dead-set on returning to the Bay Area and wanting to be in that same property, I'd seriously consider exchanging out now.
