I guess it would depend on your stock market skills, but assuming you know how to invest properly...

Selling a business often implies to customers that they are viewed as value on a balance sheet and as such is often kept private until sale is final. 

But they all have different criteria when it comes to things such as: seasoning, dscr, territory, LTV, min. property value, etc.A detailed snapshot of the deal would be needed to properly place the loan. 

So for a house like this one I would offer them $1625/month + T&I and the balance of $351k due on exercise.

One has to balance liquidity with non-liquidity (very hard to do).

Mortgages have a "due on sale" clause, which means the lender has the right to call the loan and demand full payment of the balance if the property is transferred to another person.Whether or not there are ways to legally get around that is above my pay grade, so I would advise speaking with a real estate attorney before proceeding.

But yes, I'd love to see the responses to your last question, in which you're asking to be walked through the proper procedure to make the loan from your LLC happen and use that #3 process.

Screening is imperative and very difficult to learn properly.
