Buy in cash or utilize a loan?

[Thomas Smith]

I'll soon be selling a property in which I'll be profiting around $25k. In all, I'll have around $35k to use for my next investment. I have a credit Union willing to sell a foreclosure to me for $25k. I have a couple options. I can pay cash for the property and then finance a loan to rehab the property or potentially use a business loan through the credit Union to purchase and rehab the property. This would be a BRRR situation as the ARV will be $75k with approx $20k needed for rehab (total investment $45k). Should I pay cash for the property and finance a rehab or should I finance the house and rehab from the beginning? Is there a tax advantage to either? Trying to decide on the best route to take. Any advice always welcome.
