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

so just make sure you're not excluding properties because you're looking for 'cash flow.' that's not the point of a house hack, the point is to build equity.off market deals - you can go direct to owner or connect with wholesalers and others that surface off market deals. 

The lesson learned is vetting the potential buyers before pulling the trigger on the one that might look the best on the surface.

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.

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.

As such, the only "deals" typically require extensive renovation, because anything that is purely surface level retail buyers will likely outbid you.  

Most mold is on the surface and can easily be removed with a bleach solution or one of the many mold treatment products available.

They have little to no skin in it.

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. 

It barely scratches the surface.
