All is based on personal preference. I spend 7 years selling new homes, some buyers preferred any areaway over a walkout for security reasons. Some that planned to rent their basements liked having the areaway door for easier access for their tenants, so the tenants would have their own access to the basement. A walkout condition overall was the preferred choice.
When it comes to the trees or walking trail???? This is a matter of personal opinion and the community. With a walking trail behind, if you are in a high crime area, that could be viewed as a negative, in a golf course community, it could be a huge positive.
