How do you find accurate comps?

[Marcel Pean]

When analyzing a wholesale deal, you look at comps to determine the subject property's ARV. Since I am not a licensed real estate agent I search for comps using the filters on real estate websites that show only recently sold properties. Which tools are you using to find comps if you don't have access to the MLS? How do you make sure those comps are accurate and reliable? Which number is more important, sale price or price/sf?

Thanks in advance!
