I understand the basis is all the remodel cost or labor and materials. 

Which material is best?

And does the person doing the labor get paid or only the materials paid for by the partnership?

I would also add, a contractor that you can buy materials for and they know how to put them in with little to know direction (reduces the management time of the project).

Too many flakes and dream merchants (using my material to teach while stealing your wallet and offering to help you look for it!).

I am asking anyone knowledgeable to provide any measures or strategies that could materially make a difference in heading off the risk of serious financial harm of the eviction process with non-paying tenants.

Would it be better to dispo each location independently or as a whole, and if done as a package deal does this fall under commercial or residential?

If you research recent sales you can always provide the appraiser a list of those sales.One of the best ways to insure a higher value is to update the property using materials and fixtures that are popular and common in the area.

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.

Some of the materials we choose and asked him to pick up (such as flooring) he replaced with low quality materials, I assume to keep more of our money for himself.
