Hi, not knowing too much about your situation, whether or not you have kids, on reading your post my first thought was why not stay for a while in your IP which you owe very little on (unless I read it wrongly) and buy an IP which will have a big loan – all the interest will be tax deductible.
Each time we have sold an IP we have regretted it later, not to say we would have done differently – we only sold when we had to reduce high debt or to put money into making our own (tax free) PPOR more comfortable for us with three growing boys. But selling has diminished our holding, and after a boom I think “if only we still had that house”. However, I try not to look back and realise that compared to many, we are in a very comfortable position.
We are buy and hold types (generally) and we are negatively geared, which suits us well as our IPs are in high capital growth suburbs and our losses are more than made up in growth. I know this does not suit everyone, but it suits us.
I would try to hang onto your IP. Just my thoughts.
Wylie.
