Would you dig 120 feet of trench 3 feet deep, and get the material, for $350?

You should be about 50k out of pocket—10k downpayment, 10k closing costs, and about 30k for materials and slight amount of labor (but you are doing most of it yourself). 

One lesson learned: Create a good relationship with contractor and shop around for the best pricing on materials.

Issues we faced were conflicting opinions on the next home we should purchase for our portfolio and what upgrades to do when we were doing a flip, the cost of labor and materials, etc.

Beyond that, you need to become an expert on labor and material rates in your area or get connected with someone else that is. 

The roofer gave me a invoice with high level bill of material, and a statement that it has 2 years of warranty and brand name of the shingles.It does not say brand name warranty or model or batch number etc. 

When you have unscheduled entry as an option, I think it encourages them to do weird stuff like hide stuff in weird spots, etc because they are always on guard.Hoarders clauses would have to be linked to fire codes I think for excess people and materials near fire sources, etc.

It's shedding material from impact of sun's rays, that's how elec is produced.

But if the blue sky materialized then repurchasing that equity could still turn into a win/win.

Leather is a living material and it will dry out and crack if not maintained.Microfiber is a good choice like @John Underwood said.
