The analysis column can be used as permanent reference point to the values that you calculated in your initial deal analysis.
Once you get a property under contract and actually have time to perform a detailed due diligence of all of the project costs and get bids from contractors, those values may be quite a bit different than your initial analysis.
The budgeted column gives you the opportunity to refine those values and input the actual values you will use as your project budget and repairs budget.
