Cash out refinance help!!!

[Bryan Rodas]

Hello, I'm currently trying to help my brother get a cash out refinance for his house. He bought his property like a year and a half ago, and since then, he completely fixed it. He even added an above off the ground pool, rented the first floor. Now, we want to do a cash out refinance, and use that money for the down-payment off another house. Since this is my first time refinancing the house, I need help finding a good lender, any recommendation on what to do? Important things i should ask to them? Thinks thay i shoud consider? and also whats gonna happen to my first mortgage, can we do a cash out refinance even if we already have a mortgage?
