I recently bought a house for the first time. I am in my early 50s and have a son in high school. I don't have life insurance. I have been receiving lots of advertisements in the mail telling me I should have life insurance or mortgage insurance. Should I buy term life insurance to protect my son? It is very hard for me to save money, and I'd rather save what I can for future college bills and my retirement. Thank you, Erika, Salisbury, CT
