Creative, legal ways to do this...please !!

I have a property lined up for purchase at 80% of value (supported by comps).
I want to buy it NOO with zero down.
My middle score (622) is the problem.
I was quoted 90% LTV at just over 7% APR.

Can I raise the purchase price in the contract, so 90% of the “price” is the actual sales price?
In that case, would I still have to bring funds/proof of funds for the “remaining 10%” to the closing table?

Thanks,

B.
