Taking a loan for "tax advantage" is a hugely false savings. Let's do the math.
Only the interest paid is deductible, and only if you file using itemized expenses.
Let's say you pay $5,000 in interest expense for the whole year, and let's assume it's all deductible (which, depending on your situation, it may or may NOT be - check with your accountant). You get to deduct as an itemized deduction that $5,000 in interest expense. Assuming it drops dollar-for-dollar to reduce your taxable income (and it might not - again, check with your accountant) you'll save taxes at the marginal rate you pay. If you're in the highest federal tax bracket which for 2012 is 35%, your actual dollar tax savings would be $5,000 x 35% = $1,750. Nice tax savings, right?
WRONG. You paid a bank $5,000 for the "privilege" of "saving" $1,750 on your taxes. Maybe you like the bank a whole lot better than the government (it's kind of hard to like either one, in my view), but it COST you $3,250 in real money. And if you're in a lower tax bracket, the "Cost" is even higher, perhaps much higher.
Why would you do something that's going to cost you (at best) almost 2 times the savings just to reduce your tax bill? I like to pay the smallest legal amount of taxes too, but paying interest when you do not have to makes zero financial sense.
