You're telling a just-so story, and you can tell because there isn't a simple schematic 1-2-3 story you can make from this about how these people exert control over home prices. Words mean things; wielding scarcity requires you to control enough inventory to manipulate scarcity, and REITs and corporate buyers empirically don't.
I get why people like telling stories like this: it suggests there's a single boogeyman that can be dispelled to solve the affordability problem without painstakingly goring people's oxes state-by-state and municipality-by-municipality. But it's a fantasy.
If you can tell this story in simple step-by-step form, you will. I think you could tell a story about how a large corporate buyer clears out all the marginal buyers for some thin market like an individual subdivision or tranche of new construction housing in the Sun Belt. But I don't think you can tell a realistic story for them being "a huge driving force in setting and manipulating prices" across the whole market. I look forward to seeing your attempt, though.
