Loan Preapproval for a College Student with No Income

[Jakob Claret]

I'm a college student about to graduate, and I'm looking to buy a multifamily property rental or house hack. 

I'd like to get preapproved for a loan, but at the moment I have no job or stable income. I've got a mid 5 figure stock and bond investment portfolio, but I don't know if I should bother getting a hard credit pull for preapproval since lenders care more about income than savings.

Should I still go forward with the preapproval process or should I just try to get a job with stable income and help other investors wholesale while I gather enough funds?
