I think it would be a violation. As Kathleen said, low LTV doesn't mean you can repay the loan.
1026.43 says you must consider:
(i) The consumer's current or reasonably expected income or assets, other than the value of the dwelling, including any real property attached to the dwelling, that secures the loan;
Additionally the commentary states that your ATR determination would not be reasonable if:
The creditor disregarded evidence that the consumer would have the ability to repay only if the consumer subsequently refinanced the loan or sold the property securing the loan.
