Why are all the small multifamily suddenly for sale?

[Steve Pickenpaugh]

I've been looking to house hack since 2019 in East Texas. Began by educating myself and joining a local REI. Then covid hit and everything kinda paused. I watched the local market all through 2020 and almost nothing came on market. Now within the last 10 days at least 15 small multifamily units have listed for sale. At least 3 appear to be selling their portfolio. So now I'm gun shy. Are they just selling because the market is high and they're capturing appreciation or are they rats jumping off a sinking ship? I'm still new and a little stuck in annalisis paralysis but that's how I function. If I have a tree to chop down in three hours I'll spend the first two sharpening my axe. I will buy realestate but I want to avoid the obvious blunders. What do you guys think?
