What's worth checking in person before deciding.
- This is a house, not an apartment. Check the lot boundaries, car access, and how water drains from the yard after rain, including whether the neighboring lot sits higher and could send water toward the property.
- Test water pressure and temperature at the tap, in the bathroom and kitchen, for at least a minute.
- Check the sewer connection (public network or septic tank) and the water source (public network or well), including pressure and water quality.
- Check the condition of the fence, yard, and sidewalk out front: who is responsible for upkeep, and whether there are any boundary disputes with neighbors.
- Knock on a neighboring gate and ask about noise, pets, flooding, or other issues common in the area.
- Ask to see the construction documents (permit, sign-off) and check for visible cracks on the facade or in the attic/basement.
- Check exactly where you'd park: a spot in the yard or garage, or street parking, and how crowded the street gets in the evening.
