Yes it is, but if the equity I'm my home drops, it's only on paper. I don't get to record a loss.
Yup. Once you sell the home and realize the loss, it's at that point you can write it off. Same with a stock. If you buy at $50 a share and now it's worth $25 a share, you can't write it off until you sell the stock at a loss.
However, with real estate developers, they can write off paper losses for depreciation and other things, as well. Real estate developers usually own several properties and businesses (Trump owns all or part of me than 200), and all of the income (and losses) from those "pass through" companies end up on the developer's personal income tax form. If any one or more of those companies lose money (including regular run o' the mill building depreciation), the loss can be applied to the developer's tax liability as a whole rather than keep it restricted to just the company that incurred the loss. Not only that, you can spread the losses of over several years to offset taxes on future income, which is what Trump did.
For most businesses any income and loss comes from the same source, so the writeoff happens once, in the same year, done. But for real estate professionals (developers, managers), they have a special little corner of the tax code carved out just for them (section 469 of the tax code) that lets them use depreciation and other loss deductions to offset non-real-estate income.
And you see why Trump doesn't want to release his tax returns from the last few years. Look at all the hullabaloo over one tax return from 20 years ago. Clearly, there are people who think that you shouldn't take any tax deductions at all to which you are entitled.
Kaine went on and on about how Trump took all these tax deductions and didn't pay any taxes. But when directly asked by Pence if he took any tax deductions, Kaine's hearing took a walk. Ignored the question several times.
Is not like Trump did anything illegal or unethical. He didn't write the tax code. A senator did that. If Hillary thinks this tax deduction is soooo unfair, then she had four years to fix it, but she didn't even try.
Trump did lobby for the very tax law changes that he used. Some people are aghast at that. These same people apparently think congressional lobbyists are altruistic in nature and never lobby in their own self interest. <snort>
When Trump said the system is rigged, he knows what he's talking about. He helped rig it.
