Wholesale cosmetic repair estimation

[Francisco Lucero]

Hello all, I am working on a calculator spreadsheet https://docs.google.com/.../1c28TdY7qJBJHF7Ip1yMx.../edit... feel free to copy and adjust. But I have a question, I have heard Jamil Damji say that he sometimes just multiplies the sqft by a constant number to estimate repair costs. My first stab at this sheet is setup to multiply by the total sqft of the house but I don't think that's right it seems like I should be estimating the area that needs repairs. Anyone willing to share their method?
