We moved from a doorman building to a rowhouse to a SFH and I'm also highly anxious. The things that helped me be more comfortable: Dog (who's a doll but has a loud bark), security system, knowing my neighbors and being in touch when things happen, being in the neighborhood list-serv, and.... reading tips from ex-burglers. There are tons, but some of my favorite tips (beyond locking doors and keeping cars empty) are having a radio or TV on, making sure lights are on in different rooms at night so it def looks like someone is home. My parents' home in the suburbs was cased and burgled (a few decades ago) They think there may have been a connection to a cleaning person they were using (she was lovely but had some substance abuse problems unfortunately) I think they're the exception to the rule however (they were more affluent than most folks in their neighborhood so had more valuables) https://www.amatterofsecurity.com/essex-burglary-prevention/ and https://www.buzzfeed.com/stephenlaconte/former-burglars-share-tips-to-avoid-being-robbed-reddit and https://www.boredpanda.com/former-burglars-share-tips-to-avoid-robbery/... tons out there!
