Possible Job offers or just proof of him searching for a new job can help too.
I have been living in my husband's country for the last year and a half. I sent 3 job offers, and ads online of people looking to hire in my profession, I included facebook chats of me talking to family about my return and how excited I am to come home with my husband. We showed house rental ads we have been searching for, but since he owns a house I think that will be good proof for you. You could get your family to write and sign letters or notarize them, and say they know you are coming home and have been helping you arrange to come home.
The only thing they asked for, was when our application was almost finished they wanted me to resend updated job offers to prove they were still available for me. Other than that I had no issues, and I have been jobless in a different country for a year and a half and I am the sponsor. I also wrote a letter to the officer explaining why we want to move to Canada and why I don't want to stay in my husbands country. Depending on which country your sponsor is from you can say how much safer you would feel in Canada.
Hope that helps!
