Normally contributions to an IRA would be deductible if your spouse didn't have a 401(k). But *your* 401(k) limits the ability of your spouse to deduct Traditional IRA contributions. Because there is a 401(k) available, there is no deduction above an AGI of $143,000.
I was going to mention there are ways to run rental property at a loss, but deducting those losses phases out for taxpayers with MAGI between $100,000 and $150,000 and is eliminated for those with MAGI above $150,000. So it doesn't look like that's possible either.
