The total loan origination fees on a purchase of a new home are deductible in the year of purchase or deducted over the life of the loan.
You can't deduct all of the loan origination fees paid in 2015, on the 2016 return, unless you spread them over the life of the mortgage.
For example, lets say the total loan Origination fees were, $2,500. Then $100 is deducted each year on a 25 year mortgage ($2,500/25 years = $100)
