Tenant applicant has no job going back to school

This makes it a challenge as there is no income verification possible.

I am going to ask for tax returns last few years to see previous income levels.

But without income, applicant says she has enough funds saved up.

I am on the fence on this one.

I haven't check anything yet, I will - if I decide to not reject her based on no verifiable income - then there is no point checking the rest.

What would you accept as an alternative to income?

Proof of funds for 1 year lease term, say a bank letter saying she has this fund in her account and the average balance over a year?
