Waiting for my first GPU to arrive in the mail so I can build a small miner as proof of concept. 

I had the same feeling with mine. 'Really

Since you plan to rewire anyway, the whole 'down to studs' plan makes sense, but couldn't you do pretty well with dense pack cellulose (or mineral wool) and fishing wires??? 

Let the talking heads drive down investments prices in RE and let the dumb money chase the silver miners, etc.And as was previously mentioned in this thread - the truth is that you will be most successful doing what you know.

Then I use mineral spirits on a rag to clean up the sanding dust.  

(other homes like mine rented for that much) Pull out equity to satisfy the 20% DP requirement?

And then there's the bitcoin miners.

You can always find an alternative solution - a buddy of mine rents a car when he needs a 4 door, but that seems pretty cost ineffective to me. 

I have an opportunity to purchase a 10 acre vacant land parcel at a low price and the seller says he wants to retain 10% of the mineral rights for 29 years.  

You need to look at maps prepared by the Oregon Department of Geology and Mineral Industries (DOGAMI).
