My 10c worth: you're probably stuck with painting the main building a beige colour,and then painting the guttering another colour.  The Colorbond website has a facility where you can look at a pic of a house with a certain colour roof, and recolour the other parts of the house to see how it would look.  The default colour combination they have is beige building, and gunmetal grey gutters.  http://www.colorbondcolours.com/go/bsl-colour-centre-swatch/headland .  Try the following colour combination:

Roof colour – Headland (a reddish colour)
Gutters & Fascia – Bushland (a dark grey colour)
Downpipes  & Garage – Classic Cream
Eaves – Gulf (a dark grey colour)
Wall & Mailbox – Chamois (a creamy colour)

Hi there

You might consider including Hoppers Crossing in your considerations.  It is a neigbouring suburb of Werribee which is popular due to its proximity to the Werribee Plaza Shopping Centre.  Capital Growth has been really good there – particularly on the newbuilds… and the rental return is amongst the higher rental returns in Vic.  There is the opportunity to look at DHA property investing in the area since there is a RAAF base just down the road in Laverton.  If you decide to go down that route, you would want to speak to the DHA before buying any property, to ensure it complies with what they are after, and that they would in fact lease it from  you.

Good luck
