A few key points:
1) This is pre-crisis data. Sales will decline sharply in March and April.
2) Existing home sales were up 7.2% year-over-year (YoY) in February.
2) Inventory is very low, and was down 9.8% year-over-year (YoY) in February. Inventory will probably stay low in March as people wait to list their homes.
Sales will probably be down sharply year-over-year in March and April.
Note that existing home sales picked up somewhat in the second half of 2019 as interest rates declined.
Sales NSA in February (335,000) were the highest for January since 2017.
Note that sales have been in the middle of the range recently - not absurdly high like in 2005, and not depressed like in 2010 and 2011.
Overall this was a solid report. Now, with the pandemic, sales will decline sharply.
