Deed of Trust or Mortgage:  This is the document that collateralizes the piece of real estate to the loan, so that if the borrower doesn't fulfill their obligations, the lender can foreclose.I would highly recommend having a real estate attorney create these documents for you, though a competent closing agent may have the ability.

No argument about the importance of checking the collateral, Steve.  

Since you are granting some interest in the Subject Property to another party, which is the slips to other folks, they have right and interest to know about any changes in the collateral and it's utility.  

You can do a cross collateral hard money loan. 

You might use that equity on a purchase money loan to sweeten the deal for a lender who doesn't do cash out refis on condos (blanket loan) or assign it to a seller financed transaction as additional collateral. 

They lend based (mostly) on collateral instead of credit scores. ...

However, your brokerage company will demand that you put 15% of the exercise price of the stock as collateral, which will be your investment in this case.

@Alex AlanisNot sure what your ambitions, goals, risk tolerance, or timelines but I've had a lot of success doing promissory notes collateralize by real estate in my back yard.

After you determine the project collateral adequately covers the investment, you sign the note at the bank, wire funds to escrow, and title records the note on the collateral's title.

I'm not sure what your goals are but I'd look into 1st or 2nd position notes on high equity flips secured with west coast collateral in high demand metro areas.
