Hi Archie 17
I'll vouch for Fairwater. I don't think many use this forum anymore so I don't think you'll get much feedback. I've said before in this site that Fairwater will no doubt be the stand out estate in Blacktown, because of its location, master planning with the modern design, parks, and children play areas. I also envision the value on the homes will be higher once the development is done and people see the final product. The few people I've talked to in the industry informed me that I bought well at Fairwater.
As far as Blacktown itself, I've lived in the area for nearly 15 years and have had no issues. It is slowly transforming as you can see by the high rises going up. They just need to renovate main street and get rid of all the cheap dollar shops and replace them with some cafes' and restaurants like Parramatta.
The Fraser Property sales, customer service, and site managers are quick to respond to any query or issue you may have. You can tell they take pride in their product.
I hope this helps
