Hello all, I am currently working on getting my real estate license and am also a college student. 

You’re also unlikely to get any decent financing.If the property is already zoned for 4 units then you’d need to pull permits for the work already done, have it inspected, and redo any work not up to code....which would probably be a boat load of work and time.
