Rental Profit/Loss prior to 1031

[Carlos Ptriawan]

I have a question related to the 1031 exchange. I understand how 1031 works including depreciation, what I'm wondering is related to PAL
and or rental profits.

Let's say after 10 years we have two scenarios: a net profit of 50K or PAL losses of 50K. I understand depreciation recapture as well. But how these net profit/PAL over the years impacting the replacement property that we have to purchase.

Is there final calculation for PAL or profit prior to 1031 calculation?  or are these number would be carried over to the next property as well?
