70% versus Fix and Flip Calculator

[Caroline Landreth]

There is so much difference between the results I get with the fix and flip versus 70% calculator..does anyone know how much profit the 70% is estimating for? I know this is a super general rule and the fix and flip is more detailed. For instance...looking at a single family home in need of a mostly cosmetic rehab (approx 60k to do it right for the area, this is an overestimate of 20%) with an ARV of 475k (conservative), allowing for 30k minimum profit. Fix and flip calculator say 372k for purchase and 70% calc says 272k for purchase price. Am I not allowing enough room for profit at this price point? Why the 100k difference? Thanks!
