Monthly Utility Costs in Sevierville, TN

[John Watson]

Good afternoon from Germany! I'm looking for insight on the average monthly utility cost for water, sewage, electricity, internet, and anything else I may have forgotten for a 3 BR, 3.5 BA, with pool, in Sevierville. This is my first time trying to determine cash flow on a new construction cabin we are considering. Initial numbers are 21% CoC ROI. Is this good? I used Zillow for property tax and insurance and $80 per month for Internet and Cable TV. What am I missing for expenses if I am self-managing? Thanks.
