<prompt> Human: I work two jobs, making roughly 45,000 before taxes a year and currently renting an apartment for 950 a month. My mother, who lives with her husband, plans to purchase a two-story house with an apartment upstairs. The mortgage payment would be 2300 a month.Her plan is for me to move into that house, so instead of paying 950 to my landlord I could put it towards the house, and the tenant upstairs could cover the rest. She wants me to co-sign because a property is considered an investment unless the owner also lives there, and says that I can be taken off the mortgage in a year. Are there any pitfalls I should be watching out for?  <response>: No.
