We've really like kwikset 816 key control deadbolt ($38-$45) with passage handles-- we ALWAYS remove keyed entry handles to prevent lockouts.These 816 Landlord Locks have a hidden cylinder for a master key and an easy to rekey "smart" tenant lock. 

I see some areas there is underground passage for cars under train track bridge but not all places.

.- We used to buy locks at Home Depot and just swap handsets, but now use a locksmith for same cost.2) Get rid of handset locks (use passage knobs) and only use deadbolts.- Two locks on a door really don't provide any additional security.- Cheaper as only have to rekey/replace deadbolts.- Tenants can't lock keys in their home.3) Our locksmith created a Master Key system with 10 key option.- One master key opens every door- We go 3 levels under our master, so we can submaster 2-4 unit houses and apartment buildings- Don't need a costly and difficult to secure & track keybox.

Finally, no matter the solution, I recommend using only a passage (non locking) knob and a locking deadbolt.

The opt-out process involves a notice and comment period with a March 1st deadline, which could be challenging for some jurisdictions [3].Economic and Market ImplicationsThe passage of Amendment 1 could lead to increased administrative complexity in property tax assessments and potentially create structural inequities.

@Heather Luu first, make it more efficient by only worrying about deadbolts.There is actually very LITTLE additional protection a lock handset offers in addition to a deadbolt.On the properties we manage, we remove all keyed doorknobs and just use passage locks. 

She locked herself out and was it a keyed lock or a simple passage door lock? 

Wealth in real estate is usually, though not always, made by buying and holding properties, and the passage of time. 3) Consider working for a property manager or real estate investor in the summers as an intern.

Still not a perfect system though.Also, we ONLY install passage doorknobs and keyed deadbolts.- Logically, there really is no additional security provided with both keyed doorknob & deadbolt, but a deadbolt is more secure than a keyed doorknob.- Since you need a key to lock a deadbolt when you leave the premises, tenant's can't lock their key(s) in the home and then pester us to come let them back in.--- Tenants can still lose their keys outside their home:(

By the way, that’s a very good passage and people definitely need to take it more seriously by applying themselves. :) I will share another.
