If they ask you - you have to answer honestly. You should not misrepresent anything that may influence a person's decision to buy.
If they ask about schools, for example, and you have no children, it would be fair to say you don't know. Then the buyer will investigate this himself.
You can of course use spin. 'There has been problems with youths hanging around the street corner at night but this is being dealt with by ....'
Problems with the next door neighbour? 'We don't get on with them, but that is because of personal differences and the other neighbours get on really well with them'.
But if there is any way it could be shown that you have intentionally misled, don't do it!
