Why i cash out refinance?

[Asilkan Taspinar]

Im looking into flipping multi family props but all the experienced investors seems to also do a cash out refi before selling the property. I don’t understand why they do this. They are going to make a profit anyway and probaly 1031 it aswel. So why increase the amount of money you have to pay back? Your mortgage is going to be x $ but you are also adding additional $ in debt by cashing out ‘profit’ from a refi that you have to pay back from your profits after selling anyway. Is there something im missing?
