I hate to be that guy, but have you tried the search function here or Google “where to sell photography reddit” or searching on YouTube? This question come up a lot and it usually comes down to ‘depends’ or what you are looking to get out of it/ what you’re looking to sell.

What do you feel these courses offer you that you can’t get through experience? I mean you could probably get more out of YouTube and a local photography group than these courses unless they are something specific.

You really only have a couple options:

1. Don’t bring so much stuff
2. Get lighter gear
3. Get stronger
4. Keep doing what you’re doing and deal with it.

I’m not being snarky, but there isn’t really a perfect solution for you since you can’t just attach balloons to the strap lugs and make your camera neutrally buoyant.

Dude’s not bad, but you might want to toss a NSFW warning on that link.

You know, some realtors are also photographers themselves…

Also, how do you know they aren’t paying someone to take the photos for them? There’s no way you know that unless you’re going around asking agents since listing photos are almost never watermarked.
