If any work, both materials and labor combined ,  valued at $500 and below, you do not need to have a license to preform the job. 

Would need to know the square footage of the roof to estimate the costs.If you plan to rent it out, don't use super high-end materials on the carpet and flooring. 

Siding material, interior finishes, etc.Compare solds in last 3 months then 6 months and so on.  

Sadly if they even show up to the job they are considered rockstar material these days .

The welders and boilermakers come in March 2020, and use the material provided by the fabricators. 

The restriction states no more than 10% of the exterior can be "man made material" and I would classify hardie board as this.  

If this property is historical in the sense that it is on or may be placed on a historical register, the renovation project will also have to conform to a set of conditions that will generally have to do with maintaining all or significant portions of existing architectural elements such as facades, building materials and colors.Historical or not, any planned project will have to be heavily vetted in terms of existing conditions and projected uses for all major building elements such as structural, electrical, plumbing, mechanical and ADA and ANSI provisions.

All of this is very difficult and probably not material for a first deal.

Do you get materials at Home Depot or do you use some type of supplier?

I started to create manuals and an materials book to repeat the same process with each property.
