Trade Property, Make A Quick 20k... Or Hold & Refinance?

We are in the process of completing on a property that is 26% below market value according to the bridger lending on the property. Now, if they are right, would you rather sell quickly, no hassle ( well maybe a little bit of hassle ) put it in the auction and make 15-20k in a matter of months, or would you rather do the works and refinance and keep the property maybe pulling out 70-80% of your initial investment? Let me know your thoughts in my instagram DM's @Hustlinwithhouses.
