Recently my partner and I were working with a wonderful broker to buy our 1st home, partner works and has bad credit, my credit is fair, only because I don't have much established, not because it is "bad", all was well until they found out I was a co-signer on partners car loan! then everything seemed to fall apart, as It changed my DTI ratio I am on SSI, and partner works steady, does anyone have any suggestions?

we are so discouraged right now even tho the car loan is up to date, because my credit was better the loan would have been in my name until his credit was repaired, we are living in a substandard home now and need to get out! so we are trying to move a bit fast. any suggestions would be appreciated as we are at a standstill, renting is not really an option at this point as we have cats and a dog, and because I do animal rescue, we are always temporarily working with animals at our house, help? anyone?
