We currently own our own home in California and am use to staying away from houses that were built around mid 70's due to asbestos and the complications that it brings.

Not quite the same as @Ross Bowman is suggesting, but I too am using BTC mining to off set costs in my primary residence.I live in an area with expensive costs for electricity and heating fuel, so I did the math and found that mining BTC could yield savings.

My wife and I used to live in Argyle and funny enough I went to school to be a music educator but changed directions.

I am using a cash accounting method and the unit has been rented out and placed in service for 2020, I am just upgrading the appliances and countertops.

I am using Other peoples money, non traditional lenders.

@James Hamling for someone with a lot of "experience" it amuses me that you don't even know how to fill out a purchase agreement correctly or value rehab work or even know how a syndication works.

I'm not offended at all, more amused.  

I myself am using the calculators daily to understand and get my knowledge of the numbers.

What contracts do you use for these deals (clearly I am used to thorough contracts in CRE, but I know in wholesaling residential real estate you can do so with a 1 page contract or double close)3.

I am using the wholesaling with an agent approach and they won't know the sqft either but will mention that the house is on a "so by so" lot and priced accordingly.
