Should I borrow money for renovation on a purchase rental?

[Watson Josue]

Hi My BP family,

I'm on a 90 days challenge to buy an investment rental property. I am currently in the process of buying a duplex that should be closed by end of November. Since this is my first time, help me with this question: 

The purchase price is $100k with a 25% down. I only have the down payment available. I don't have any available cash for renovation. I want to do some works on the property in other to raise cap rate. How can I go about finding the money to renovation if I don't have any more cash?

Thank you.
