I am considering a purchase of a Quad unit in Ocala from Southern Impression Homes with management by SunCoast Property Management.

That's up to my operatione manager.

She also mentioned that they’ve been in real estate since 2006 and have managed over 30 properties (though this is more of a side business for them), which suggests a mom-and-pop operation.

With a few tweaks to the management structure, and with new leadership, I figure we can greatly increase the revenue.

Quote from @Erick Pena: A "good" rental property is one that covers all expenses (mortgage, taxes, insurance, maintenance, property management fees, and any other costs) and still leave a surplus (commonly referred to as cash flow).Calculate cash flow as: Cash Flow = Rental Income − Operating Expenses − DebtThere's much more to it, but that's the basic idea.

Build a strong team, including agents, lenders, and property managers, and use tools like the BiggerPockets calculator to analyze deals.

I am a local agent, property manager, investor, and house hacker in SLC area.

( Regarding interior, and not HOA, management, location)Anyone has experience renting for snowbirds?

However, like most property managers, once in awhile they do have investors interested in selling and at that point, they may reach out to their clients about that sale. 

We will manage their annual rentals once they are completed.
