Title: Physicians are missing out on major tax savings with the wrong mortgage
I’ve run into this myself with a couple properties—sometimes you think you’re getting a great deal on a mortgage, but the tax angle totally changes the math. Especially if you’re in a high-cost-of-living area, like the Bay or NYC, even a “regular” mortgage can rack up enough interest to make itemizing worthwhile. But I’ve also seen folks get tripped up when the SALT deduction cap hits... suddenly those big state tax payments aren’t helping as much as you’d expect.
One thing that’s always made me pause is how quickly things can change year to year. Like, if you refi and your interest drops, that deduction shrinks, and suddenly the standard deduction looks better. Or if you pay down your mortgage aggressively, same deal. I got caught off guard once after selling a rental and losing that extra interest write-off—I just assumed I’d still be itemizing, but nope. Had to rethink my whole approach for that year.
Curious if anyone’s ever really dug into whether a 15-year vs. 30-year mortgage makes a big difference for this? I mean, the 15-year saves on total interest, but you lose some of that deduction cushion each year. Wondering if it’s ever worth stretching out the loan just for the tax break, or if that’s just wishful thinking... I’m always a little wary of making decisions just for tax reasons, but sometimes the numbers get close enough that it seems tempting.
Anyone else find themselves second-guessing their mortgage setup after running the tax numbers, or is it mostly set-and-forget for most folks?
I get the temptation to stretch out a mortgage for the deduction, but honestly, I think that’s a bit of a trap. Here’s why I’m skeptical:
- The tax deduction only offsets a fraction of the interest you’re paying. You’re still out way more in interest than you’re getting back, especially over 30 years.
- With the standard deduction as high as it is now, a lot of folks don’t even get much benefit from itemizing unless they’ve got a really big mortgage or other deductions stacked up.
- SALT cap, like you mentioned, just makes the math worse for high earners in expensive states. That deduction isn’t what it used to be.
- I’ve run the numbers a few times and, for me, paying off the mortgage faster always wins long-term—even if I lose some deduction. Peace of mind counts for something too.
I get wanting to optimize, but I’d rather have less debt than chase a tax break that’s shrinking every year. Maybe I’m missing something, but I just don’t see the upside to dragging out a loan just for the write-off.
