Prolonged enthusiasm can be exhausting (failed offers, tours, travel) one way to remain engaged is to stay connected and in constant communication.

Any travel nurse is a brother or sister in my field, so my plan is to make sure their housing is everything they could imagine in comfort and necessity be met.  

BNA airport has crushed expectations on travel numbers...and no not including the "post covid" revenge travel. 2 - I can recommend a few.

I am considering purchasing a condo in Stamford, CT, to use as my personal residence, as I'll need to travel to CT frequently—about 50% of the time.

@Robert Brown personally I'd avoid Sosua, as it's a destination for sex tourism.There is also Santo Domingo, which attracts business travellers as well and the nearby beach city of Juan Dolio.

The HOA has an exterior insurance policy for the condos (Image 1).

That's ~12% Cash on Cash return which seems pretty good/decent.My concerns are by doing this, it would reduce my rent price on the main house (most likely since they'd be sharing with other tenants on the property) and also I'm unclear whether adding an ADU would negatively affect the value of the property.Option 2Consider converting the property into a short/medium-term rental, specifically to travel nurses.

Here in NW Florida, there's tons of options to house hack really nice homes if you rent by the bedroom or separate in law spaces through MTR to military or traveling nurses. 

We acclimated the flooring, but I suspect the existing tenant may keep the house at some very different temps (when she travels I suspect it's quite cool in the winter just warm enough to keep pipes form freezing, and very hot in the summer).  

They cater more to traveling professionals.
