I don't mind increased rates for outcall. Makes sense due to extra time and effort on the provider's part.
Separate from the in/outcall factor, there have been several threads/discussions about rates, which many people feel are a bit out of wack - and have been since COVID. Personally, I think some of the high rates we're seeing are due to new providers who don't understand the market, and they're buoyed by new hobbyists who still have extra money laying around.
One thing I've noticed is providers with high rates and few reviews don't seem to last, so yes, I think reviews matter.
I'm defining high rates in this market (DC) as $700 or more. That said, I can't think of the last time I paid over $600.
I personally can't think of what a $700-$1000 an hour provider brings to the table that a $400 provider doesn't bring. Exceptions for specialty work of course, but that's not my scene.
A provider could have two dozen 10/10 reviews and I can't imagine myself paying $1200 for an hour with her. But I'm not a private-equity-venture-capital-finance guy with a 7-figure income. Maybe for those guys, $1200 an hour makes sense. But a string of 8s and 9s will convince me to consider (note I said consider) spending $500 and maybe even $600.
Disclaimers:
1) I endorse providers charging whatever they wish.
2) Over time, the market will decide what the appropriate rates are.
3) We're definitely in an inflationary cycle - prices for just about everything are high right now.
