While there are numerous things that you can do to improve the value and selling potential of your home, there are several external factors that are outside of your control. These impediments are especially important to consider when you are purchasing property because they are not factors that will easily be fixed. 
There are two categories typically outside of the control of remediation that may decrease your home's value: proximity and location, and lot features. The first set of factors that may decrease your home's value fall into the category of Proximity and Location Factors; location factors refer to the location of your home and it's proximity to desirable and undesirable features. Because location factors that devalue your home are based on where and how your home is situated, there is generally little you can do to improve these factors. This lack of potential to improve and increase value means it's especially important to consider their impact on resale value when purchasing. If these factors do not deter you, or you are willing to oversee certain devaluing features, these devaluing factors can be used during negotiations to secure you a more favourable purchase price. 

1. Proximity to good schools 
It is important to consider your home's proximity to good schools as this can often increase the value of your home as well as the neighbourhood as a whole. Parents often consider school district catchment as major determining feature of their home purchase, they want to ensure that their home falls within the catchment of a successful, high-calibre school. Buyers who do not have children may be aware that this impacts resale value and will factor it into their decision. 

2. Proximity to transit
Many buyers consider a potential home's proximity to transit as a key selling feature. If there are grocery, produce and butcher stores all within walking distance, this is a great selling feature as well. 

3. Proximity to main road or access road
Lot location on, or near a major road poses a risk for children and increases overall noise; access roads have pose the same issue.

4. Proximity to train, major highways or airport 
Like major roads and access roads, trains, highways and airports significantly increase noise pollution, making it less ideal than comparable quieter areas.

5. End of cul-de-sac of t-intersection
Houses that are at the end of a cul-de-sac or t-intersection will suffer from having car headlights constantly directed at their house, oftentimes right into living room or bedroom windows.

6. Neighbouring properties in disrepair
A neighbouring property in disrepair poses a twofold threat of devaluing your home: it is an eyesore that negatively impacts the value of houses nearby and it may often be a sign of other potential problems with the neighbour.

7. Backing onto power lines, trail, path or greenbelt
There is a lot of inconclusive and conflicting research on the hazards of proximity to power lines; whether you believe that proximity to power lines pose a potential health risk or not, many potential buyers do and this will decrease the value of your home and make it harder to find a buyer.

8. Issues with lot
A. Corner lot
B. Lot irregularity
C. Comparatively small lot
D. Slope of property
E. Presence of stream or river
