Transferring without taking spring semester classes?

Hello everyone,
I currently have 45 credits at a CC and am applying to transfer to a couple of universities (1 public, 1 private) for Fall 2020. All the schools I am considering have a min credit amount of around 30. The classes I am currently missing are not needed prior to transfer. I am just wondering if it would look bad/negatively affect my admissions chances, if I did not take classes in the upcoming Spring semester so I can focus on working before Fall 2020? I know answers to this question will vary school to school but I am trying to hear about other people experiences. Thank you all very much for your time !

In general I think that this is fine. Lots of students take a semester or more off for a very wide variety of reasons.
