I feel your pain! A friend of mine and I have several storage buildings full of props and animations, and I have been just trying to get a loan (in addition to the cash I am putting in) to pay for the rent, actors, insurance, advertising, etc. I went to my bank with a 40 page business plan, and blew them away with the presentation. When I left the second meeting with them, I was under the impression that they were going to fund my entire haunt. Then--- the phone call came. Due to a "lack of liquidity" of the items in the haunt, the SBA wouldn't back the bank, so the bank wouldn't underwrite the loan.
The bank had no doubt that I would succeed, because I was so prepared. However, if for some reason I did default on the loan, they said that the people who would be trying to sell the assets didn't know enough about the stuff to be able to get any money out of it. They actually said to try back after the first of the year, because the SBA funds were overtaxed, as you said.
I wasn't planning on opening until 2010 anyway, but it is frustrating. I have found the perfect location, but they will only lease in 1 year blocks, and I need to get the funds secured before I can sign the lease.
I do well in my day job, but not wel enough to take on a monthly lease payment that large. My wife and I are both searching for ways to fund the haunt, and if we come up with anything, I will pass it along to you.
