I'm not seeing rates going much lower than 5% in the near future.

However, from the stories I've heard it so far, sounds like it can lead me to the life I want for my future if I play my cards right.

You might also consider talking to the tenant about shifting the rent due date to the first of the month to avoid future confusion and align with typical forward-paying leases.

I'd plan to save any profits each month for future CapEx, repairs, vacancy until we had ~20K for this house set aside.

Once i have the network established, I might consider STR in future.

Your zoning should be ok, but you want to do everything by the book (which can be costly) to percent future insurance claims or injury claims in an unpermitted basement living space. 

Your questions are fine, but I would be more worried about the asset and the future cap ex than the renters in general.
