Do you verify their income?

If they haven't, verify that a signed lease agreement will be counted towards your income.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

The moral of that story is stay persistent, don’t quit, and trust but verify. 

You need to fully understand all the numbers on the property and verify they all make sense and that the numbers meet your criteria for a good investment.

How do I go about verifying her income from the VA?

@Summer Dechanukul If your agent really represented that the home was in good working condition and actually told you that you didn’t need an inspection to verify, you should report him to his broker and file a complaint with the state real estate board, maybe talk to an attorney about a civil suit for damages against the agent and broker if they misled you.

Verifying last 2 years of rental history very important!

Did the underwriter not verify that you had the funds to close before allowing you to close the loan?
