residential redevelopment spreadsheet

[Kyle Callahan]

Hi, investors - I've been a BP member for a long time - have planned for years to create an Improve and sell practice.  My goal - buy properties and improve them for resale.  We're based in Boulder, Colorado.  The thing that I hope sets us apart is that we will consider sustainability is as a principle driver in the redevelopment - so air sealing, insulation improvements, new windows, doors, high performance mechanicals, solar arrays, ground or air source heat pumps, resiliency and resilient spaces (think covid inspired zoom rooms, home learning centers).  To make this pencil out, we will expand properties, of course sustainably with re-sourced materials, passive heating / cooling design strategies.  All said - I need to track the expenses and costs, buying, selling, holding, improving.  Is anyone aware of a good, free or cheap spreadsheet to help organize this endeavor?  Much appreciated for any advice.
