Best avoided if you can. If you can get a different house with own drive, clearly that’s better.
As people say, so many different scenarios. Many new build estates have lots of parking problems, because even if there is private parking, there are also shared parts or spaces or access to the private space/drive is shared and people don’t always leave access free or have the same expectations about what is right.
Even where people have their own driveway and parking, but it isn’t separated by a fence or similar, issues appear. There was a thread about a neighbour wheeling their bins down the neighbour’s drive, because of the way they parked.
The best drive ways have own private access and are clearly distinct from other houses due to wall/fence/hedge etc. However, it only tends to be larger detached houses which are built like this these days,so increasingly semis and terraced houses have some aspects of shared parking or access to it.
Of course it can be okay with good neighbourly behaviour…but you can’t guarantee this. And when you come to sell, future buyers will have the same concerns you do.
That said,most people have to compromise on something when buying. Depends whether this is the thing you can compromise on for other positives if the property, or if this is a deal breaker for you.
