That's a nice idea, lets expand it.
Some houses could be reinforced. With steel locks, stronger doors, and metal bar windows. That would require some costly investment of course, but could be used to store best stuff.
Now during base raid, such house obviously would attract all the attention. What to do with it?
1) it could be ignored
2) it could be destroyed. Time and energy consuming process, howewer falling roof and other constructions would ruin 10-30% stuff inside
3) it could be torched. Will take some time to burn, (less with straw thatching roof

) but in result 80-90% stuff will be destroyed
4) it's lock could be lockpicked and doors opened without much of the struggle above. However lock-pickers stealth skill will compete with lock quality, determining chance of success.
Stealth skill would have more use. Steel would have more use. Base raids would be more interesting and diverse. And on top of that, every good raid group should have dedicated locksmith.
