After a few hiccups with the certification work and around 3-4 valuations (lost count) I finally have the last of the numbers to finish this thread. Thanks to my MB Pete for his peristence.
Costs
$263,000 House- purchase, BA's fees, stamp duty etc
$3,000 Set Up costs - fence, maintenance, repairs etc
$98,000 GF - construction, planning, approvals, clothesline etc
$364,000 Grand Total
$540 Weekly Rent- $300 House and $240 GF
$340,000 bank valuation made late October
8.2% yield based on purchase/set up costs
$13 net cashflow using an interest only loan of $364,000 at 6% and other cost such as rates and insurance.
Was it worth it and a good idea?
With the aid of hindsight and more education, no. The best choice would have been to buy and keep as much property as I could get my hands on a year ago and ride Sydney's property boom.
As it is, this property is a great addition to my shrunken portfolio and is a good asset to acheiving my long term strategy. The experience from this baby development and stepping out of my comfort zone has also been very valuable and is currently being put to good use.
Thanks To
A great team that included my BA, MB, builder, planner, PM and other SS members for all the excellent help given, advice, hand holding and patience. As small/simple as this GF/House build was, there is no way I could have done it successfully without this team.
