You have posted some very good photos, and I`m sure you will be able to make a lovely garden there. My very first thoughts though are regarding possible flooding. Have you double checked if there have been any previous issues ?
In a village near here where we live there is a stream similar to this one in your garden, and sometimes it floods and causes problems in homes that are close by. That hole made by the previous owners indicate that they may have been rather worried about this.
Wow, thank you so, so much for this!
We asked a while back about the history of flooding from the stream and were told that in the 11 years they've lived there it has only been 1 meter up the garden. However they haven't answered when we asked what the hole was for!
The house doesn't have a basement and the inspector who looked at the house didn't find any water damage, however the hole is indeed suspicious! The geo data site says very little risk of flooding, but I don't know how they determine that.
I have contacted our realtor who is going to have a thorough look into it. I'm glad we have a professional on our side!
If we risk it and still buy the house, after our guy has determined the history, we have good insurance that will cover both future damage and if there's already damage there that the inspector didn't find.
Still, a flooded house (or garden for that matter) would be horrible!
Again, thank you so much for your help!
