Investors & landlords

Thanks again for all the valuable responses. This may be my last question on this. I did not deduct and don’t have any maintenance related expenses. Question is only on mortgage interest and property tax paid. Are these two deductible if the property was not available to rent and listed for sale? Also, Turbo Tax is deducting the excess expenses carried over from last year. Is that allowed to deduct this year if property was not available to rent?
