C/D neighborhoods always look better on paper, pro forma style, but A/B tend to be safer bets to actually perform. 

Was all baseboard radiant then I changed the bathrooms to euro style wall mount radiators due to changing space around and they worked great too. 

Some of the bigger brokerages may have more support, training, and systems in place to help you get started, while a mom and pop style may provide you better access to the broker to ask questions when you get stumped or have more comradery as @Steven Wilson hinted towards.For example, at my local Keller Williams office there's technically 600+ agents, however the top 50 or so are the ones doing all the transactions, showing up to trainings in the office, and running teams within the brokerage so there's still been plenty of support in my case.

There's a great amount of lousy listings to compete with, which is encouraging, but that's partly a product of it being very hard to get properties improved, decorated, cleaned, etc.

Ex:  "Two Chicks Investments"  (owned by 2 women) leaves a cute little 2 bird decoration at each house they sell. 

A crossfit gym or a regular commercial style gym with the climbing niche you speak of, I think would likely do a lot better.
