There are two well known posters on this site that are in OH, and only licensed, so that in itself is not a reason to not move forward.
However, read through some of the threads on this site about how everyone is starving for work, and that alone makes this NOT a good time to get into this profession.
Personally, 4th Q 2022 saw me have my 2 (and 3 of 4) slowest months ever as an appraiser. So unless things turn around quickly in 2023, may be really hard to even get enough work to get your hours in, even IF you find a mentor.
Best wishes to you though.
