People do weird things all the time in old houses to reinforce sagging roofs or floors that dont actually transfer load to the foundation but visually cure the problem.

I believe the pre-treatment of choice is called "sizing" compound which is applied over a sealant or primer.

This isn't a business, this is opportunistic treatment of old people in need.  

Properties that you acquire for rehab/flipping do not technically qualify for 1031 Exchange treatment. 

This is the prescription phase, where you show the Seller that your service is the best available treatment, taking all the factors of the Seller's situation into consideration for their pain.

Not doing something properly, like the correct treatment of net cash flow is a problem for both.

What are the differences in treatment for various mold or is there?

You can try to use the "paper tiger" tool that first perforates the paper surface, then apply the liquid / steam treatment.

Ignoring is the best treatment for any kind of sexism. 

Just turned off my TV and wondering if anyone knows what software does the property brothers use (or something similar) to visualize how the property will look after renovation.
