Fixed Costs- What am I doing wrong?

[Daniel OKeefe]

I've put together a spreadsheet to analyze fix and flips. Using the basis of ARV-Rehab Costs-Fixed Costs-Profit, or simpler ARV x 70%- Rehab Costs. I've broken down my fixed costs into purchase costs, holding costs, selling costs and financing costs.

The issue I'm having is that on my typical analysis (around $350k ARV where I live) my fixed costs are coming in around $60k which is making my offer price laughable. Am I calculating something incorrectly or is that in the ballpark of what the fixed costs should be for a $350k property?
