I would like to share a very valuable spreadsheet with you that I have used to develop quick and accurate budgets for a remodels/flips.
The spreadsheet has a checklist of work items that are typically seen on any ordinary remodel, and unit prices for each. All you need to know is the quantity of work items and plug it in and the spreadsheet will automatically calculate the total for each item.
The spreadsheet is also capable of some more detailed analysis; here are some of the other tasks it can accomplish:
1. Can analyze the budget based on self performing some work tasks and subcontracting others. For example, if you think you can paint the entire house yourself, then you place an "x" in the self-perform column and the spreadsheet will automatically calculate the work item as self-performed (material only) and as 100% subcontracted (labor & materials).
2. Can tabulate work tasks based on trade using the autofilter pulldown. For example, you may have a tiling contractor, a carpenter, or a HVAC contractor on your project. By using the autofilter pulldown, you can tabulate items that are to be performed by the carpenter throughout the project to easily build a scope of work and budget for that trade.
3. Can tabulate work items based by the subcontractor. This is very similar to the "trade" autofilter except you can organize the work tasks by the subcontractor that will be peforming the work. For example, you can highlight autofilter "Bill's Plumbing" and it will tabulate all of the work items being performed by Bill's Plumbing and show their budget for each item.
Overall this is a very helpful tool for evaluating potential properties and for managing scopes of work and budgets during the remodel.
