I sold miners (mostly open air 3-4 GPU AMD based).

I would prefer not to bring in another agent because I calculate my wife's 3% into the deal.We use the long standard NC Offer to Purchase and Contract, Addendums, Mineral, Property Disclosure, etc. - do I have to use this or as an investor, is there a better way to write a shorter offer that is compelling and doesn't take so much time? 

i sent you a message invite as well but as a newbie in this encore career of mine (RE investing) im interested in contract / freelance work (im a brand / marketing expert) or even just doing admin + bp calculator work lol LMK  

Miners, oil and gas workers, etc.?

I am familiar with some of the differences, feel free to reach out to me to discuss (for example, in the US you own the land and minerals under the surface, and the air above the property you "buy" (this is called the Allodial System), which is different from most other countries except a few.

I have mineral wool batts in the walls.

And even people selling a ton of land in those areas have a hard time unless they are also selling Oil, Gas, Mineral rights. . . those are usually sold already though. 

You make your money when you buy, not when you sell.ControlOne of the biggest advantages to investing in real estate opposed to any other asset class is that you are in control of the land, the mineral rights beneath the land, and the air rights above the land (a form of God's money).

That, and since this is California, is there any water (and/or mineral rights).

These are licensed and registered people and firms.According to the SEC and FINRA a "broker" is any person engaged in the business of effecting transactions in securities for the account of others.Events or actions such as helping a company sell shares to raise capital, engaging in other activities like participating in presentations and negotiations, making recommendations to investors concerning securities, receiving transaction-based compensation (i.e. commissions or finder’s fees), and continuing or regular involvement in sales of securities are evidence of activities rendering a person a broker.The term ‘‘security’’ means any note, stock, treasury stock, security future, security-based swap, bond, debenture, evidence of indebtedness, certificate of interest or participation in any profit-sharing agreement, collateral-trust certificate, preorganization certificate or subscription, transferable share, investment contract, voting-trust certificate, certificate of deposit for a security, fractional undivided interest in oil, gas, or other mineral rights, any put, call, straddle, option, or privilege on any security, certificate of deposit, or group or index of securities (including any interest therein or based on the value thereof), or any put, call, straddle, option, or privilege entered into on a national securities exchange relating to foreign currency, or, in general, any interest or instrument commonly known as a ‘‘security’’, or any certificate of interest or participation in, temporary or interim certificate for, receipt for, guarantee of, or warrant or right to subscribe to or purchase, any of the foregoing.Finders can avoid registering as a broker by limiting their activities to:Introducing prospective investors to a company without engaging in negotiations.Not recommending the company’s securities to prospective investors.Basing their compensation on a flat fee that is not contingent on the closing of a securities sale.You can find most of this on line on the SEC website.
