I had a similar question but there is one more nuance. I assume what you describe applies to origination points, which are amortizable for both, rental and personal property. But what should one do with mortgage costs other than the points, from the earlier refinances? All those application fee, underwriting, appraisal, recording, etc. Unlike points, they are neither amortizable nor deductible for personal property. Can one recover/amortize those prior mortgage costs after converting the property to rental?
In the case of original poster, he refinanced in 2011 and 2015, both times while the property was still in personal use. Then he converted to rental. He will be amortizing the origination points, but what about all those application, etc. fees?
