It depends on your preference and attitudes.
A corner house will have only one side common wall, and one side free . This will be beneficial when some repair etc has to be carried out. Moreover this will be preferable if there is a window or ventilation facility one the corner side.
However this can be nuisance if the place is used for playing and you do not like noise and disturbances.
However when there are old and sick people in the home it will be helpful for them to have neighbour on both sides who can be easily contacted and have some interactions.
However it may be good to have a house where from you get a good view of the people going around , like a road, ground or passage. That will make you feel less lonely but at the same time sufficiently private also.
If the house is near gate,and if there is no security personnel, then you may get disturbed and feel less secure.
So take consider of all parameters and decide.
Personally, I will prefer a house where ventilation and cross ventilation are available and there is minimum common wall to share.
