I started building a house at the end of August and it got finished up the first week in January. It was a construction loan up until January and then it was converted to a mortgage. Do I need to repo

Your question was cut off, but maybe this information will help.

You can deduct the interest on your construction loan as home mortgage interest if the loan was secured by the property you moved into. 

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 date that construction begins.
