Metadata
It seems really strange you lock your front door but are happy to share photos. Every photo you share on the internet contains metadata which can locate you to a certain point ( just parked at work !!) now your house is free as your wife just shared (look at the kid's going into school) your house is now a target!
2016 What happens your house can be found (192.com) as you are both out of the house.
Your names (electoral roll are both shared) your location is known.
Do you empty your bins ( Credit card offers ,Bank statements )
I could apply for lots of things with this information Name,Address,Bank Account Years at property (Land Registry) Gives you the value which you paid for your house.
Seems we all could read the terms and conditions of what we share (And who you Employ !!)
