It sounds like you’re on a good path considering refinancing for a lower rate.

Sounds like you're in great shape to dive into the real estate world.  

Sounds like you are a valuable asset to hosts in your area!

My question is, does this sound like a good plan to start off our real estate investment journey with as little debt as possible?

It sounds like you're in an exciting spot with your real estate journey.

I know it sounds simple, but good PMs do not deal with bad areas for the most part.  

If the guests don't answer or sound shady, cancel them, that's our rule of thumb.

Getting the sellers profiles sounds good, but not generally allowed.This might bight you later when the platforms realize you are not the original owners.I'd get everyone's contact info and tell them you are setting up new profiles under your name with your bank account etc. and ask them to rebook under the new profiles.Then I would offer discount pricing to start with to get more reviews and build your brand.

The online options sound attractive with Solera.

I understand you're a realtor, but this sounds like an extremely niche property.
