@Duke Hartman I feel your pain. Been there. Done that.
To add to what @Ken P. said, taking out a loan from your 401K plan is a great option... you might even be able to spread the repayment over 30 years since the purpose of the loan is to purchase a house that you will occupy. Regardless of the term, you can repay a 401K loan at any time without penalty.
Some other options to consider since you only need the loan for less than one year (assuming you can get a HELOC or cash-out refinance as source of repayment)...
(1) Borrow from the cash value of your whole life insurance policy. PROS: quick access to cash and virtually no transactions costs. CONS: Interest rate is relatively high (expect 7% - 9%) and it compounds over time. ONLY USE THIS OPTION FOR SHORT-TERM ("BRIDGE") LOANS because the compound interest effect is NASTY and the tax implications if you fail to repay is EVEN WORSE.
(2) Use private money (i.e. borrow from friends and family): If you know people with idle cash this is your best option because you set the loan terms. Of course you should formally document the transaction with a note and pay reasonable interest to compensate the "lender" for use of their money and risk associated with the transaction.
