Freddie Mac's Home Value Explorer

[Raj Tirur]

I tried to get a HELOC from a Credit Union and they gave me an appraisal based on the Home Value Explorer that was below what I thought I'd get. They list the comps they use and they were mostly much higher values than my house and mine has more bedrooms, baths, and is bigger than most. I don't know if its worth getting them to visit my house as the comps should tell the story I'd think. Has anyone had luck with this Home Value Explorer tool?
