For those that are not familiar with lending, a major component to the crisis a decade ago was banks had to liquidate assets because they did not have sufficient reserves.

If we don’t hear from you before Mar 26 at 9:27 PM, the request will expire and the reservation will remain active.

Or has it expired and they are monthly?

., what steps are you taking to fortify your finances to reduce the risk of a liquidity crunch?   

One could enter with gloves, mask, bucket of cleaner and an e-cloth mop head to wipe down the walls. 

My financing contingency expires in five days.

Important to note: If the Tenant/Buyer fails to make payments for 60 consecutive days, beginning on day 61, without any notification needed the Tenant/Buyer may lose all rights to this said property, plus all prior payments made will be forfeited to Seller/Landlord, and be considered, “liquidated damages”, plus this “Lease To Own” Agreement will be considered “null and void” on day 61". 

That preapproval has since expired. 

This will encourage large banks to continue to write mortgages, since they don't make their money on interest charges, they make their money through origination and servicing fees.The rub, of course, is that there's no way to know what happens with liquidity and the direction of the broader credit market.

If these questions make you nervous or defensive then I think you have your answer on whether you should proceed with the deal or not.If you have the liquidity to be able to do this, then as Evan said, you still qualify and should go through with it.
