YES!!
Shaun Moore has a great quote about this on his podcast regarding the current market. He says something like "people are quick to give themselves all the credit when things are going well, and none of the credit when they're not". Essentially people succeeded when a blind monkey succeeded and they think it's because of something they did, and then when things start taking a reasonable level of competence they don't have they start blaming it on the broader market, convincing themselves it's impossible to make money in this market.
And it's not even that the market is poor now, it's just really good instead of really really really good. So these people bought at the right time, they think "I'm freaking awesome at this", and then when things start to settle a little bit back towards normal they start blaming everything else. "It's the economy!". When in reality they're just saying they suck too much to do this when it's just easy to make money, instead of when it was super easy to make money.
I hate to pick on the guy, but Robuilt is kind of an example of this, though slightly different. His returns are actually pretty poor relative to the market he bought them. He basically bought at the right time, and now makes the majority of his money teaching and on social media. His STRs barely bring in as much revenue in total as many of us here generate from 1 or 2 properties. The dude bought a $3M Scottsdale mansion at the peak of the market that generates $12k-$15k revenue per month in the HIGH SEASON, and people are lining up to pay for his course on how to do it, totally blind to the notion that it only works for him at all because of the tax benefits it provides for his large teaching/social media income, and any of them would be bankrupt after making a purchase that bad.
