Large portfolio through turnkey provider?

[Keaton Reiners]

Hi everyone, still doing my research on how I want to jump in to REI. I'm curious how feasible it is to have a large portfolio (50+ units, mostly SFH) under a turnkey provider? Does anyone on here have experience with building a sizable portfolio, either under a single turnkey provider or multiple? Has anyone been able to do this with REI Nation specifically?

I'd love to hear about how people were able to scale over time, and how the TK provider was able to assist with that. I'd love to here any experiences or advice! Thanks!
