Pro Tips

Always cross-reference: Use at least 2 sources. Zillow + County records is a good combo.
Trust county data for facts: Square footage and year built from CAD is most reliable.
Photos tell the truth: Always look at listing photos to verify condition - a "3/2" can be builder grade or fully renovated.
Bookmark your county CAD: You'll use it daily. Most have mobile-friendly sites now.
