You should be receiving tax relief at source onthe interest paid on the 100k mortgage on the PPR, albeit it only at the 20% rate
So in essence you are at most losing the difference between the 20% rate and the 42% rate (if apporpriate) plus PRSI
One option depending on when the investment property was inherited would be to sell the investment property pay off personal mortgage and purchase another property using a mortgage
This could involve CGT but
will include stamp duty, solicitor fees and estate agent fees
This will more than likely make it less profitable to do
You would need to calculate it
Or another option would be to purchase another investment property borrowing the full purchase costs between the existing and the new and use this to reduce the tax liability
Again youwould need to calculate is this was profitable or not
A third option would be to purchase a tax incentive property, possibly a S.23, to "shelter" the income
If the taxable income is around €12k p.a. this again might not be financially advantagous
There are some options but most will include doing something a bit more constructive than obtaining a mortgage, unfortunately
