There’s more than one way to skin a cat and the one that resonates with me is the BRRR strategy.  

The first part of Mold remediating is stopping the moisture issue  until you figure out that part don't bother with step 2 . 

There are more than one way to skin a cat. 

Kind of like raising earthworms or Ostriches for skin care oil.  

They also make those moisture meters, that I have had roofers use in my attics to attempt to trace back sources.As noted, in my market, if you have active leaks that you are aware of, they need to be disclosed when selling a property.  

Mold requires moisture and a food source (dust is sufficient).

As a retired CPA, I have seen more than my share of bankrupted RE investors who were over leveraged with many properties.All the more reason to emphasize developing good due diligence practices, having some skin in the game and staying on top of legal requirements, maintenance, finance and tenant screening criteria.

And then I said, supposing you brought the light inside of the body, which you can do either through the skin or in some other way.

When you're new with no experience, It will be extremely hard to find anyone that will go into business with you if you have no skin in the game, and you don't know enough buyers and sellers to be an efficient wholesaler. 

They have little to no skin in it.
