Transfer of title and mortgage – Getting married

From my reading of your post:

a. your fiancee's IP is in her name and her father's.  If this is correct, how is the rent being shown in their tax?  If her father is showing rental income from the property then if he transfers his share in the property there will be CGT consequences unless he has previously, say at the time of purchase, entered into a contract to sell his share.  What shares do they hold the property in?

b. if you get a second place, is this going to be a PPOR or an IP.  If an IP, the ownership will depend on yours and your fiancee's financial situations and plans.  eg if the property will be negatively geared it may be best to be in the name of the highest earner, but if you think it is going to rise in value and your fiancee is going to take time off work for children in say 5 years and you intend to sell it when she is not earning other income maybe it should be in her name. 

It sounds to me as though you’re missing one vital thing here: You’re yet to take out a mortgage.

If you’re hell-bent on buying another property, you would do well to consider getting your own on the FHOG, and then transferring it into both of your names after the first 12 months are up. If you’re able to do that right now!
