Can rental losses offset against the conversion of a traditional IRA to a Roth IRA?

I have a rental house that I had no income but did have expenses for the first 3 months of the year. The house was occupied but I had to get legal help to evict the tenants.  After repairing damage caused by the tenants I decided to sell the rental house and it was sold  for less than my basis in the house.   
Can either of these losses be used to offset the ordinary  income of the conversion of a traditional IRA to a Roth IRA ?
The only income I have is social security and some interest.
