We'll see regarding the rate hikes, there are a lot of different opinions on that. There's some optimism they'll come down due to the current spread between the 10 year T note & mortgage rates - historically this spread is around 170 bp higher, currently it's about 300 bp due to the economic uncertainty. Honestly I'm just being optimistic so I don't have another slow year next year.

Although we were due for that after 2020-early 2022.
Million dollar question regarding the market "health". The real estate market is the most imperfect market that there is (heterogenous goods, so much emotion involved in SFR purchases, etc.) so it's almost never "healthy" in the eyes of a lot of economists & other people who look at this for a living.
In my opinion there just needs to be some sort of event which brings in a bunch of inventory to the market, the shortage of supply is creating a really difficult environment for most buyers right now. How this event happens? Who knows. Possibly by a recession & people needing to sell homes, which is obviously not ideal for most.
People also need to probably come to terms with the fact that we're not going to see +/- 3% mortgage rates for the rest of our lives - this new "high rate" environment is new to so many people that have bought homes over the past 15-20 years, so there is a prevalent feeling of "there's no way I'm selling my house with a 2.5% 30 fixed rate". This makes perfect sense, I'm not planning on getting rid of mine either. However, life does happen & factors such as needing to upgrade/downsize, move, death, divorce, etc. always take place.
The issue with continuing to increase rates is this "shock" feeling of elevated rates will only be exacerbated. Also, at some point, affordability has to come into the picture - if rates go up to 9-10% it's going to be hard to afford a home for most people.
I'm mostly just spit balling here. I keep up with it because it affects my job, but I'm not close to an expert. If you're looking for a good podcast on the housing market, BiggerPockets puts one out called "On the Market" that is pretty good.
