Ok so, few things:
1. Pricing trends will be whacky for late 2020 and early 2021 due to the low volume nature of our slowdown, which will lead to volatile pricing trends, especially when getting granular
2. Pricing trends are lagging, representing a market 4-6+ months ago when considering when that deal was signed. So its a rear view mirror look at the market
3. Condo is best represented in PPSF, coops do not have size data for the most part so Coops are best repr in Med Sales Price
If you want to compare them both together, try Med Sale price trend first, here is what that chart looks like -
