Unsecured Business Line of Credit and Your Credit Score

[Brian Wood]

I have a small business and my bank offered me an unsecured line of credit of 60k at 5% with no annual fee.  I already have a home equity line of 180k at 5.5% that I'm not using.  My small business does pretty good and I have decent amount of cash on hand, but I'm looking to start investing in real estate and don't quite know what strategies I'm going to do yet and don't know how much money I will end up needing.  

If I go with the line of credit does my credit take a hit?  I'm a sole proprietor so I'm not sure if my personal will be linked to the business line of credit.
