Does anyone have experience with Ivory Home’s predesigned materials packages?

all materials, all labor costs to others, Not you, utilities, interest payments, permits, licenses, auto/truck expenses, tools needed are all deductable. 

I have spreadsheets filled with material lists for every phase of the build that includes pricing for materials as well as labor, and sources that I use for them.

This is the only app I can find customized for tracking your hours and that of your cleaners, handymen etc... Anyone have any experience with it?

@Alecia Loveless is correct--tenants need access 24/7 to their electric service panel, water and heat, assuming those are individual utilities for each unit. 

Would love to hear your applications and utilize them within my business.

Utilizing empty lot space in this way helps to combat the increasing housing prices and limited supply many markets have been experiencing.

For example, the iconic Malibu waterfront homes were built directly over the water, many by variance, and assumedly will not be permitted to reconstruct, certainly not with the same materials or attached architecture.

Quote from @Account Closed: I would say.. can you save the tub and re-glaze and redo the tile on the wall can save you $1,000 or more just on materials and labor..

I'm going off the understanding that you still need to spend 500+ hours in the business to achieve material participation (please correct me if I'm wrong).
