What if you can not find comparables?

[Kurtis Powell]

Hello all. I am in the process of trying to research comparables for a property, and I can not seem to come up with any. I have used Zillow and I also use Realeflow which then uses Zillow, and still nothing. I think the problem lies in the fact that the house is 6 bedrooms, 4 baths and over 3000 sqft. This is pretty big, so I think it is just that there are no like properties to compare it to? Does anyone know of any other way I could find comparable properties without the MLS? Any advice you could give would be much appreciated! Thanks in advance!
