Any unevenness causes them to unlock.

On an empty house the water company will have the meter unlocked, but not in the open position.

I feel like there must be a company that makes an app or technology for smart phones where someone (like UPS or FedEx) can call you and you can unlock an entry door from a distance.Much thanks!

The market is definitely stronger now (in part due to out-of-state investors) but Round Rock can be tricky.I'm originally from the Chicago area where you can count on 6% appreciation per year like clockwork since WWII but I'm finding Texas is a whole different animal with negative appreciation mixed in with weak and strong years depending on the most recent oil bust or dot.com bust.The last few years have seen a lot of zero down entry level homes being sold with ARMs that are about to unlock after the inital 3-5 year period.

Had a realtor leave my door wide open (not unlocked but WIDE OPEN) for 2 days.

It is another $10 each time you unlock it.

There are simple slide locks on the doors entering this common room from each unit.  2nd floor can enter the common room by unlocking their door, but cannot enter through the 1st floor common room door because its locked from the other side. 

we charge $25 for unlocking. so we rarely get calls. when we do, we collect the $25. sweet!

My first thought is, is there equity in your home that a refi could unlock?

Then treat them as the same.Sometimes in bundled packages such as this, there may be value to unlock in buying the group and then selling the units individually.
