It seems to be same as the investment: if you gain, you must pay immediately; if you loss, you can only report $3,000 a year. Some may spend the rest of the life to get away the loss from internet bubble!
In the rental, jjj7 said seems to say you can't report any neg income but rather carry to next year. The flip side might be you will turn positive sooner or later.
BTW, your depreciation is 5K, but rent only 15K or 1,250 a month? Say 27years of depreciation 5Kx27 = 135K so you are not at 1%?
