Loan on tax sale property

I have bought a hand full of properties in Tennessee at tax sales. In this state when a property is purchased the deed goes into the purchasers name shortly after the auction but there is a one year right to redeem, then the buyer can file a motion to quite title with the court to get an insurable deed.  I have properties that have passed the redemption period and are in the process of clearing the title, but that can take 6 months to a year.

Is there a lender out there that would loan me funds on a property before the title is quite?  I would like to reinvest some of the profits before the 2 year window.  Even if I could only borrow 50 or 60% that would help me speed the reinvestment.  If someone would do that what terms should I expect? If not Tennessee, is there another state?

Just a thought.
