That's not what the word predatory means.
Usually that has to do with things like pricing (both initially and any future increases), handling of maintenance, problems, and of things like late payments, etc.
You're looking at it once again purely through the lens of how it affects the existing owners. For example an existing long term owner in the area would not be considered predatory based on your criteria no matter how much price gouging they engage in.
But they could still do that. The only difference is, more people knew who the story was coming from.
Why do you want them to be able to obfuscate the source?
