Limit to repairs for financing?

[Kori Bundi]

Hi everyone! 
I found a duplex in a great neighborhood that needs substantial repairs. And I’m super new to investing…and totally lost. I’m wondering if anyone can tell me how many repairs are too many to qualify for financing. I think these units are close to a tear-down, but with the asking price, I will have quite a bit of cash on-hand to handle extensive repairs.
