Credit score while investing

[Antonio Russo]

How bad would my credit score hurt if I took out 100k against my home? My credit score is 735 and my home value is 609k paid in full. I also would like to know what you would do in my situation? Would you take out a mortgage on your rental property and continue to takeout mortgages on different properties OR pay the rental in full and use the tenants rent to pay off your HELOC faster? I need help! Please. Im new to this. Im really worried about my credit being run so many times by different mortgage companies then being rejected!
