What makes you reject a property before doing the full analysis?

One thing I've been thinking about while working on FixerFlip is that investors probably spend too much time analyzing opportunities they should have rejected earlier.

Sometimes it's not about finding the perfect deal.

It's about quickly recognizing “this isn't for me.”

For me, that might be an unrealistic renovation assumption, questionable comps, or numbers that only work under very optimistic conditions.

What's your fastest deal-breaker?
