My dad said he would be willing to cosign with his very financially prudent son.I could wait a little while longer untill I am out of school and making income myself OR I could view this as a great opportunity to decrease my liability (on paper) while having 100% of the benifit.If I were to co-sign would it decrease my debt ratio for so that I could more easily obtain more home loans in the future?
