I think that in your case Muli that a home loan with a Mortgage Offset account is probably your best solution.

I think Line of Credits are excellent facilities when they are being used for the purpose for which they were intended.
However, I think that your main aim is to pay the home loan off in the soonest possible time frame, rather than using the equity in your property to accumulate assets such as shares.

Down the track, into the future, if you do wish to purchase shares and you do want to use the equity in your property to do this, then it would be a great idea to have a Line of Credit added to your loan facility. However at this stage an Offset Bank account gives you all the benefits of the LOC, with a lower rate of interest being charged. LOC’s are really something to look to in the future, rather than being something which will suit your current requirements.

I hope this helps you in making a decision.
