We likely will need to up our tenant key count soon but we switched to LL Locks around 2012 (maybe it was 2013).  6 sets of tenant keys for 6 years with 19 units, I will take that any time (but 8 units of the 17 LTR units have not been turned over since switching to LL Locks - very slow turn over).I would investigate the option in the link you provided and compare the features with LLL to determine if the one in the link supports everything LLL supports. 

Home features 2050 sq ftm 3/2/2 with a over 500 sq ft basement and a 24x24 shop.

SmartKey just refers to the rekey feature.

@Marcia MaynardI have personally never liked the idea of a basement bedroom and most houses in the neighborhood don’t have this feature either.

I don't know why but I do know the top contributors feature can change Quickly.

., to get a vague idea of a house’s features, photos, and value.

However QB online is not exactly the same as the desktop version and I get the impression that it is not as full featured. 

Good tip there.I will be adding a nest, and it will be linked with an alexa (for multiple reasons, including security features).  

BP does have a search feature, you can look people up in the Temecula area.

Maybe this list could be a feature of Biggerpockets @Mindy Jensen - just a thought?
