(a)Nonrecognition of gain or loss from exchanges solely in kind
(1)In general
No gain or loss shall be recognized on the exchange of real property held for productive use in a trade or business or for investment if such real property is exchanged solely for real property of like kind which is to be held either for productive use in a trade or business or for investment.
(2)Exception for real property held for sale
This subsection shall not apply to any exchange of real property held primarily for sale.
Google depreciation by gift or death，看了几篇文章，好像gift / death 都抹掉。不同的是，新主人的depreciation basis，如果是gift，要用旧主人的depreciation basis，但是重新开始；死后的depreciation basis可以用死时的FMV。
Now, if you acquire property in a 1031 exchange and later attempt to sell that property as your principal residence, the exclusion will not apply during the five-year period beginning with the date when the property was acquired in the 1031 like-kind exchange. In other words, you’ll have to wait a lot longer to use the principal residence capital gains tax break.
能不能卖两个或者三个投资房，同时把钱1031到一个贵一点的房子？我知道1031是可以一换三的，但是三换一可不可以？
还有就是1031后新买的房子，如果不做长租，做Airbnb, 也算是符合1031条件对吧？

到后面就不太敢讲价了 只追求按时close
出租房1031 置换成另一个出租房， 再出租两年后变自住房，增值及折旧就可以不交税了吗？

其中还有不少因素自己难掌控，比如市场房源，对方买家/卖家存在诸多变数，或为了凑这时间也只能价钱上退让，这样算下来1031 Exchange未必划算。
During the extended 60 days time seller has the right to close upon 10 days notice to the buyer. 这样延长closing time 可以找房， 找到后可以迅速成交。
