Investment property with CGT over 10 years…confused.

Your loan repayment expenses you can claim only the interest payment.
You haven't mentioned depreciation claim for the renovations. Get a quantity surveyor to survey the property to work out what you can claim as depreciation. Repair done during the income earning phase can also be claimed unless it is an improvement and then depreciation is used.
if property is owned jointly by two people then the 100k gain is 50k each . If the 50% rule still exists in 10 years time then $25k
Now depends on your marginal tax rate if it was 30% each then 25k * .30 =7500
if owned by one person 100k  gain is 50k if the 50% rule still exists in 10 years time then $50k
Now it really depends on your marginal tax rate in ten years time say if it was 30% each then 50k * .30 =$ 15,000

I agree with you that negative gearing is a bit of a dud but imagine you pay more than the interest payment over ten years.
lets say you pay $428 per week on a twenty year loan  at 9.47% p/a interest rate you end up after 10 years with a loan of
$150,000 .
Now imagine you pay 520 per week on a twenty year loan  at 9.47% p/a interest rate you end up after 10 years with a loan of
$66,000
Now over ten years do you think the rent is going to remain the same ?
$184 * 52 = $9500 a year minus say $2000 for repairs and costs
leaves 7500 a year. Now based on a 10% p/a interest rate once your loan gets down to 75,000 you are no longer supporting the loan the rental income is paying down the interest cost. remember this is if the rent remains the same and doesn't rise.

This is what I have been doing for the last 15 years and in two months I will have my first investment house paid off completely.

Based on 80% LVR I could borrow $800,000 for my next investment property and the rental income from the first property will help pay for the second property.  

A negative gearing strategy works well if you can borrow and experience a boom property growth like in 2000 – 2003 where properties grew between 10% to 20% p/a depending on what area you purchased in.
I have experienced years where the growth was stagnant but with the boom growth my property has grown by 7% p/a averaged over 15 years.
I did purchase another property in Cranbourne , Vic in 2000 for $100,000 and sold it in 2005 for $170,000 that was a 70% increase in 5 years but that was during the boom period. That property is now worth $220,000 to 240,000 that's in 3 years another $50,000 I missed out on because I sold but I knew due to my circumstances and forecasting that I could not afford the $400 a month shortfall , about $15,000 in 3 years due to not having a job.
 
Country properties will experience less capital growth than city properties but the entry costs are less.

I recommend you buy Australian Property investor Magazine.

Property investing is more about building wealth over time rather than selling a property in 10 years time and losing any more capital growth..

it is hard to buy a positive geared property in this market but you can eventually make a property into a positive geared property by paying the loan off.

No. You should approach this in a balanced and measured fashion, much as you've already started to do here.

No.

No! , If you claim the expenses each year against your rental income or wage income you have got your tax deduction already !

If you then try and claim the expenses as a CGT loss or to increase the cost base and against income each year , this is referred to as double dipping on deductions and isn't claimable by the ATO as you can only claim deduction once.
