Hello Lisa

Thank you for your advice

That meant: we can pick the year to use it. Correct? Just not care about loan officer, who are not tax expert. 

I am trained about mortgage loan a lot in the past which they suppose to add back depreciation and amortize $$$, NOL in past, but some they dont know 

Because I search , there is other Turbo tax expert said "Use it or lose it" . Then some one else argued that "Pub 536 did not mention at any where "

I rechecked with pub 536 and did not find one either. 

Thank you again
