After inspecting a few of these recently, and seeing their long market history (often with several agents) it makes me wonder why buyers purchased them in the first place. Unfortunately, in a frenzied boom market (as Sydney experienced in 2002-04) I suppose buyers thought that anything standing would make money and, for some who went on to resell whilst the going was good, it did. However, it's pretty sad when you see these same properties listed some five years later, sometimes for less than what they paid, still languishing on the market. Whilst this list is pretty general and by no means exhaustive, a list of "dog" features that I would consider detrimental to a freestanding home in a suburb would include: Close proximity to high tension power lines and stauncheons Close proximity to visible ugly water pipes/conduits and artificial waterways Close proximity to sewerage/garbage/water treatment facilities Close proximity to shops/industrial/commercial infrastructure Main road position No backyard or level area One living area in a 4bedroom house Unusually lowside/highside position in street Incorrect or off-putting floorplan (eg: living all downstairs with kitchen and bedrooms upstairs) I'm sure others can add to the list, and I guess it comes down to personal taste in some instances, but I do believe that, as an investor, you should be aiming to cater to the biggest pool of both buyers (resale) and tenants alike. Avoid those dogs!!
