Requesting assistance on financing

[Nicholas Zumwalt]

I am looking to invest in a great multi family complex, have already talked to the owner and we have signed a letter of intent and so now I'm in a rush to get the financing locked in. I have equity in my primary residence but not the best credit score (under 580). My question is this : am I fooling myself and wasting the sellers time or is there a way I can still close this deal? And if so, how? Thank you everyone in advance for your advice and inputs. Note: this is NOT a post to try and raise money! This is a post on seeking advice and guidance.
