Investing with bad credit?

[Jovani Bautista]

Greetings, I am new to using Bigger Pockets, I currently own a duplex rental property in the Denver, CO area. I have owned this property for about 9 years now, which I bought when I was 21 years old. For the first 7 years my Dad managed and completed repairs for me. Things have changed (negatively) and now I am trying to get steady/good tenants and complete costly repairs in one current vacant unit. Along with the fact that my credit has hit rock bottom within this past year and other personal financial challenges I face. I know I have plenty of equity with this property and have been told to try using that equity as collateral, but I doubt I'll be able to do much to anything investing wise with my poor credit score and recent financial issues. I feel stuck as to if there are any realistic/quicker options for me. Credit can take some time to rebuild, but I would like to take advantage of my current equity position. Any advice would be greatly appreciated in advance.
