Owning your own home

Water pressure can be fixed but it costs money to so. But if you need to re-do the heating and whatnot anyway you can get it addressed at the same time.

Boiler...just budget to have to replace it. You will anyway. It's just a matter of time. The thing I would look out for on it would be where it is actually is positioned, they type, and what it is plumbed in to.

Windows - if they are double glazed then in a pre-offer visit check for panels that have lost their seal. If they are wooden frames you can eyeball for rot on any visit.

As above, on a first visit, only things like massive cracks, obvious rot / damage, damp and mold are worth noting. You are more scoping out for fit with your desires and whether you could grow in to it and extend it in the future.

On a second, third, pre-offer visit then obviously running the taps, shower, opening windows, moving furniture and whatnot is more reasonable.

Have a good look at the neighbours, things broken with the house can be fixed but you can’t change the neighbourhood or location. If you see a house that feels right, check the area out at a few different times of the day and night.
