What made this opportunity particularly enticing was my prior experience managing this exact duplex for the same investor over a span of three years.The property itself is a 1950s duplex that underwent significant renovations in 2017.

I don't ask for SSN and also personally have never provided/been pressured to provide them myself when I used to rent, and honestly don't want to open up liability for having to keep someone's SSN either.

She then applied it by visiting them before we had any official agreement, or me providing them permission to go on the property. 

A multifamily unit in Providence might be your answer.

I know of an outstanding provider of such properties in the FL market.

I've been searching online for trying to find a loan servicing company that provides the services in Florida.

Just look at what services are available at your address.Spectrum is a quality provider so you are trying to lower cost.Check out https://www.broadbandsearch.net/ and you should be able to see what's available in your area.

we have until spring of 2025 until our balloon loan either has to be refinanced or paid off (we got this loan because we intended to build, of course) and now i feel like it's a ticking time bomb.we conducted "clean and satisfactory" (no issues whatsoever to build) soil and foundation tests and provided those to every buyer. it seemed (not quite sure here) like they backed out once they reviewed the tests - yet there is nothing negative in them. we will not be providing these tests moving forward (as we had to do them ourselves and feel that each buyer should do their due diligence moving forward!)

Someday I would like to possibly have 4-5 homes that I would be renting out that could possibly help me retire a little early as well as provided continued cashflow in retirement.

Your insurance company can provide referrals for this in your location.
