Tax auction/Financing

[Jeremy Winright]

Hello! I'm a agent in michigan just starting out with investing. I was exploring the idea of tax auctions to purchase my first flip. unfortunately with the purchase using cash I have very little left for reno. I now turned to the mls and will have to get financed for my first property. Which is the better option? Using cash or using the banks money? If cash where can I get some extra for renovations?

Thanks!
