@GregJJunge,All the zips you mentioned are among the more preferrable zips, excluding 06, 08, 09,19 and 54.

I like to rent to "untouchable" applicants like these with something in their application that excludes them from 90% of the market as long as I can get a premium rent amount for doing so and adjust for the risk.

And if rent gets too high, people who can buy will buy instead, except for those who are excluded from the market for whatever reason.
