Best tax outcome?

I bought my PPOR early this year and rented out half of it. As I've been saving hard and putting the $ to my offset account, I've managed to reduce my loan to half recently(with most of the $ sitting in the offset account). At the same time, the PPOR value would have grown by at least 10% based on nearby sales.

Therefore, the tax benefit of claiming half the cost of interest & depreciation on the property now seems less attractive compared to reducing how much CGT I might have to pay when I sell the PPOR in future. 

I'm just wondering, what would be the best options for me? 

Should I continue renting out half the PPOR but receive it as cash in hand and not bother about claiming tax benefits. In this case, I would only have to pay CGT for the period which I claimed tax.

Additionally, am I correct in assuming that any depreciation that I've claimed should be added back to the cost base of the property when I sell it?

Any advice is very much appreciated. Thanks.
