I think backing on to a park or across from a park is a plus to many, however if the park is connected to a school or community centre than it could be a big drawback due to noise and traffic.
Being on a golf course is a personal preference. There's the prestige aspect and it's nice to look at a nicely manicured landscape, though there are alsothe annoyance and damage due to flying golf balls.
Ravines or protected wilderness areas are I think the best, but some don't like the wildlife and bugs that are associated with them.
Pools are a definite negative due to liability and maintenance.
Houses on corner lots are a hit or miss to certain buyers.
Some don't like them because there's less privacy, especially if it's on a busy intersection, and if it has a sidewalk there's twice as much to shovel.
Some like them because you don't feel boxed in by neighbours on either sides, the house has more light/windows/views, it gives the house a more stately appearance or presence (especially if the garage could be tucked around the side), and the lot tends to be larger.
Some agents say homes on corner lots sell for less, but I don't think it's really true. Yes, it could sell for less but it could sell for more depending on the buyer. I personally prefer homes on corner lots.
