JB, We back on to the course and spending a bit less than that. 35sq open living and 4.2x4 balcony on the back. We have compromised on a few things, mainly carpet. We choose not to spend to much on carpet (we have a 2 yr old and want to have a second). We thought that we can replace the carpet in a few years. We have tiles and may one day move to floorboards but given the little ones we didnt want to have to stress.
We focused on the things that cant change or not easy to change. We made sure of an upgraded stair case, big showers, big kitchen (lots of pot draws etc), linen cupboard space, walk through pantry,
We upgraded our taps and CS benchtops etc... I dont think what you are spending is unrealstic (but I am not a wiz of the market). The scary part is the landscaping, you can spend a fortune but never get it back. Something neat, easy to maintain I beleive will get you the same as the house next door that spend 10's of thousands.
Check out the commbank they use myrp data which shows capital growth. You will need to put in Cranboune South. Has a range of data and median sales prices etc (currently showing good capital growth, high 30%'s)... - http://www.myrp.com.au/getFreeReportPag ... etCode=FSR
The Herald Sun a few weeks ago also had details on when the median prices is particular areas were due to hit $1m. Cranbourne South was July 2017.
Hope this helps....
My view given the access to the city, mornigton and the new bypass... We are on a winner. The course was also in the Top 100 in Australia last year. The youngest course in it and it will only improve with time (number 64)
