Yes, as long as you meet the following requirements:
"You can fully deduct points in the year paid if you meet all the following tests. (You can use Figure B as a quick guide to see whether your points are fully deductible in the year paid.)
Your loan is secured by your main home. (Your main home is the one you ordinarily live in most of the time.)
Paying points is an established business practice in the area where the loan was made.
The points paid weren't more than the points generally charged in that area.
You use the cash method of accounting. This means you report income in the year you receive it and deduct expenses in the year you pay them. Most individuals use this method.
The points weren't paid in place of amounts that ordinarily are stated separately on the settlement statement, such as appraisal fees, inspection fees, title fees, attorney fees, and property taxes.
The funds you provided at or before closing, plus any points the seller paid, were at least as much as the points charged. The funds you provided aren't required to have been applied to the points. They can include a down payment, an escrow deposit, earnest money, and other funds you paid at or before closing for any purpose. You can't have borrowed these funds from your lender or mortgage broker.
You use your loan to buy or build your main home.
The points were figured as a percentage of the principal amount of the mortgage.
The amount is clearly shown on the settlement statement (such as the Settlement Statement, Form HUD-1) as points charged for the mortgage. The points may be shown as paid from either your funds or the seller's.
Note.If you meet all of these tests, you can choose to either fully deduct the points in the year paid, or deduct them over the life of the loan."
"Home under construction.
You can treat a home under construction as a qualified home for a period of up to 24 months, but only if it becomes your qualified home at the time it is ready for occupancy.
The 24-month period can start any time on or after the day construction begins."
