This tenant has lived in the home for 10 years, and pays a VERY low amount in their monthly rent. 

Craigslist, Zillow, local property mgmt company, etc) because not one of these sources by themselves is entirely accurate.Specifically, with regards to Rentometer, keep in mind that it does not even factor in how many bathrooms a home has, the condition of the home, size of the home, or even type of home (apt vs SFR).

This forced appreciation with a heavy value-add should be great with a long term buy & hold play.2) Cash out refi & purchase a vacation home via a 2nd home loan.
