Can you deduct mortgage interest during vacancy while fixing up a rental?

[Tiko Z.]

I have an investment property with an investment loan that was vacant for a few months while I fixed a bunch of issues and got it rent-ready. During that time I was still paying the mortgage, taxes, and insurance.

My question is: can you deduct the mortgage interest and other holding costs during that vacancy, assuming the place was intended to be a rental the whole time and the work was to make it rentable (not a major rehab)?

Just trying to understand how this is typically handled and what others have seen in practice. Appreciate any insight.

Was it rented out before the vacancy? if so then obviously.  
Was it your primary home before the vacancy? Then probably not.

If neither of those are true then almost certainly. I don’t think you’d have to capitalize them like you might any pre-rental repairs/capex.  If this is the case I would expect your tax guy to say yes. But my only concern would be this late in the year you probably wouldn’t get a tenant in before the end the year, I defer to your tax guy as this year the property would have no rental income.  LMK what he says if this is the case. Hopefully it’s situation one instead.
