4plex I think your analysis, while a good exercise, is not indicative. Homes historically have not sold at prices necessarily reflective of their GRM. Close but not precisely.
For example this house at $445k less a 20% down payment. This results in an approximately mortgage of $2134. Take out your deduction for interest and property taxes and you are paying close to what you would rent this place for. That’s how buyers look at it and why it might be a good deal.
To answer the other question this is indeed “Bay Ho”. But Bay Ho isn’t really recognized so in MLS it is listed as Clairemont.
