Aside from those already mentioned, just being tired of running an STR could trigger it.

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

@Amaris Benjamin any of the options @Chris Seveney mentioned would be solid starting points.

Additional relevant provisions in the contracts:"Title Evidence and Insurance: a title insurance commitment issued by a Florida licensed title insurer, with legible copies of instruments listed as exceptions attached thereto ("Title Commitment") and, after Closing, an owner's policy of title insurance (see STANDARD A for terms) shall be obtained by the Buyer. 

You mentioned a possible remote walkthrough and purchase - are you local to this area? 

As another mentioned about finding a better rate with the previous owners company, gone are the days of just automatically renewing insurance and a good syndicator should be shopping around for the best coverage/premium atleast twice a year.

I also forgot to mention my gratitude for your service.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

It seems like I will start to get fees that were never mentioned if my balance drops too low across all accounts (!)

The reason I mentioned this is many in the situation are not great at saving money.
