The rate of burglary is 271 per 100k per year in the US but nobody doubts it exists. If the rate of weasels ripping off deposits was 1 in 20 which is incredibly high and you sampled 10 instances the chance of getting zero is 0.95^10. That is to say the chance that someone would rent 10 times in such a market and not have someone try to rip you off is ~60%. Your sample size isn’t meaningful even if it were random.
