Rashad,
For one deal a year, I'm not sure if it's worth it.....
I'm in Indiana, so I don't know if it's similar in Texas.
It cost me about $500 to take the class. I took in online and had no complaints. Working a full-time job and going to class at night or on the weekends didn't appeal to me.
I've only held mine for a little over a year so I'd need to go back and look at expenses to be sure. But, I think the test was $20. Joining my local board was about $1500. Then I pay quarterly MLS and Supra fees, maybe $500 a year. If you google your local board they should have the fees on their website for all to see.
But, I'm hoping to deduct this all as business expenses, because, well, it is. Also, I did 2 deals last year and recouped the fees with my commission.
Now, here's the part that is rough. I had a managing broker at first that didn't care for investors and didn't offer much help. I just switched last week. It caused me to lose money by making poor pricing and negotiating mistakes on my own deals. It's different, I'd guess, when you are new and making mistakes with other people's money. Not that it doesn't matter - but this stung because I was responsible.
That is also not to say that I couldn't have hooked up with a sub-par agent and also missed out on profit. So, I lost but oh, man - did I learn. And that, is priceless. I also told you that I have started to craft my own strategy and it is greatly helped by being an agent. When all the fish are swimming in one direction, go the other way . ..
Lastly, many of the agents I've talked to say 'yeah, I work with investors' but they really don't frequently enough to work with you well. Save for one or two that are the real deal (like your agent you mention), many really don't have a good idea of how it works or are put off by the process and I don't blame them. So, yes, as you say you can spread out some wear and tear by using multiple agents but this strategy didn't work well for me either.
I also tried the 'go with listing broker' strategy but I was vulnerable because I didn't fully understand comps, the process, etc - and didn't know what to offer and they weren't 'on my side' and couldn't be for obvious reasons. If you are targeting foreclosures/bank owned properties, some of those listing agents can be the tough to work with.
Whew, that's it.
