It's highly unlikely, if not impossible, to find a traditional lending source to fund the purchase of tax deed property. There are a myriad of reasons why, but the risk involved negates any profit potential for a traditional lender. The minimum six-month to two-year redemption period is also a major problem for a lender.
If you don't have your own money, the best method is to raise private capital. Although you don't have a lot of experience, you could look for a fix and flip or BRRRR investor, partner with them on a purchase and split the profits. Solicit other investors looking for a solid return, self-directed IRA investors, or basically anyone that currently invests in real estate. Before beginning the process you should speak with an attorney to ensure your strictly adhering to the law.
Identily a property that you would purchase and your target acquisition price and work out the ARV to show the potential profit spread. Create a graphic and post messages on social media and to your sphere of influence looking for a "funding partner". Be prepared to answer a lot of tough questions about the risks and the process in general.
On the plus side, having to pay cash and be at the auction in person usually roots out the "know nothing" buyers that drive prices up.
