From there its really dependent on the language in the sales agreement.....Does the sales agreement contain a liquidated damages clause? 

There are a lot of details you haven't filled in in this post (which is fine), but you will likely need a key principal to co-sign loan and a contract with an experienced property management company.The key principle will co-sign the loan to help show the net worth and liquidity needed for the underwriting department.  

Stocks are pretty liquid, BUT selling them triggers tax consequences and the timing of when you want the money for real estate purposes might not coincide with the best time to sell the stock.

You could invest in a commercial syndication or you could put your money in a safe/liquid investment, so when the bubble pops you're ready to pounce.

(personally, I use a brokerage account so I can get the pretty risk-free 5.25% in a money market fund that is completely liquid).To be blunt, if you really are limited in funds...

This in essence to pull liquid cash out for a second investment, and transition the property into a long term rental.
