Looking to buy a house??

I'm a student in college looking to buy a small house nearby. The problem is I don't have proof of income because I work for a lady doing house work. I have saved about 6 months and or can provide a sufficient down payment. My dad has offered to be a co-signer (pretty good credit). I also have my fiancé that has proof of job stability. What are the chances of me getting approved since this is an odd situation??
