My top recommendation is to begin by contacting property management companies in each target area.

Aside from downpayment, you want to have a solid emergency fund in place, something that can cover unexpected repairs, vacancies, or any other random costs that pop up.I’d also recommend saving more than you think you'll need and keeping a close eye on your expenses.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Most professionals will recommend a separate LLC for every $1 million in assets, but I don't think that's necessary.

Always recommend doing a soft-pull especially since not sure exactly when you'd find a property but you can get qualified and get some estimates.  

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Since they've lived there so long, I recommend giving them 60 days to move as a means of softening the blow.Third, don't negotiate or accept excuses.

Is there any form of education you could recommend?

It also depends on how you hold your properties; LLC, S Corp etc... as to what the agent will recommend.

I’d recommend connecting with local property managers and agents as soon as possible—agents can help you identify deals that fit your BRRRR criteria, and property managers can give insight into rental demand and market rents.
