I'll give you a few reasons.
- Typically if you're working for a company as a W-2 employee, lenders will ask for 2 years of tax returns, but more importantly, they'll also ask for your last 6 months of pay stubs from your current employer; which holds more weight as to how much you will qualify to borrow.
- Also, lenders were a lot more strict post-housing bubble burst as far as debt-to-income ratio (also known as DTI), but now they've become a little less strict in terms of figures. I've routinely seen loans get processed with up to a 42-46% DTI. Every case is different.
- The article also assumes the Buyer is only looking to qualify for a conventional loan. If the Buyer qualified for FHA, he could put down $7k on a $200k house, and have the other $23k serve as reserves so the lender knows he has additional funds in his account.
Not saying the person in the article would automatically qualify for the loan he is seeking, because again, every situation is different; but to say he absolutely wouldn't, given his situation, is incorrect.
