Any benefit to waiting for summer?

I've heard from a lot of people that trying to find a place in summer is a nightmare as demand is higher and so are prices. Brokers are telling me that right now is a great time to be looking.

But, I don't feel like there's that much listed right now. I'm checking street easy/zillow every day, but apart from a couple of listings I'm not finding anything I like.

Questions:

• Am I delusional regarding how many places are available rn or are others feeling this?
• How much more inventory can you expect winter into summer?
• How much are rents likely to increase winter to summer? closer to +$100 or +$1000?
• Is holding off for a few months worth the extra hassle of increased competition and higher rent, just to see more inventory?
