Cash out refi on 4 unit apartment building in Minnesota

My credit score is around 640. I need to do a cash out refinance on a four plex that I renovated. Property value is $500,000. I owe ~290k on it. Looking to do as high cash out refi as possible so that I can pay down the accrued debt. Conventional/commercial would work. I used credit cards and personal loans to finance rehab. Email me jestin dot sorenson at gmail dot com if you have products that would work. TIA
