As you know The Mexican state grants a mining concession (a permit to explore and exploit minerals in the subsoil) so I have 3 gold mines in store but no idea how to sell it, any ideas?...

There are States in the US that have bills to legalize it as money, others want to buy it and put it on their States balance sheet, others want to attract miners, other States including California and Colorado want to make it possible for citizens to pay government fees using bitcoin. 

I've moved back to Columbus after going thru divorce and getting rid of all properties and am getting back to doing what became a passion of mine - real estate investing.I'm hoping to meet new investors and create something great, sustaining and damn near awesome.

They are finally charging miners for start-up capacity infrastructure costs (about $200k) and have increased their rates above the industrial rate actual manufacturers like Alcoa were enjoying, but they are still getting better rates than us residential peons. 

Completely rehabbed the front dwelling (2bd, 1ba Folk Victorian miner's cottage) top to bottom and added 1/2 bath.

Try Titan Bank in Mineral Wells (Dallas).

Texas does have a 180 day redemption period unless the property is a homestead, has an agricultural exemption or is a stand alone mineral lease, then it is a 2 year redemption period.  

Collections and DelinquencySec 34.21 (e)(e) The owner of real property sold at a tax sale other than property that was used as the residence homestead of the owner or that was land designated for agricultural use when the suit or the application for the warrant was filed, or that is a mineral interest, may redeem the property in the same manner and by paying the same amounts as prescribed by Subsection (a), (b), (c), or (d), as applicable, except that:(1) the owner's right of redemption may be exercised not later than the 180th day following the date on which the purchaser's or taxing unit's deed is filed for record

I have found through my search of mineral records that the address listed above was owned by someone else and the address was different in 1905.The MLS is far more accurate, because you can locate information you need that may be as little as minutes old.
