My house is a bit older than that - 1730's.
It's beautiful and full of character.
Some key points however. Get a survey and by this I don't mean the basic mortgage survey.
We paid over £3k for ours and the surveyors were there for a full day, inspecting everything. We got a 200 page report.
It's a lot of money - but the thing with very old properties is that whist most issues can be fixed they can be hugely expensive to do so.
This is especially true if the building is listed as any repairs have to be done on a like for like basis using traditional tools/methods where possible.
Damp isn't necessarily a huge problem - it can normally be treated but you need to get someone specialist to look/assess/quote before you commit.
You'll face other issues down the line. For example all my windows (26 of them) are non standard sizes. Replacing them meant each one had to be hand crafted. It cost over £50k for the entire house and obviously UPVC wasn't an option (not that I wanted it). The same issue meant virtually all my window treatments were custom made. Windows were just to broad but short for ready made curtains/blinds.
Fitted rooms - kitchens specifically, can be tricky as room dimensions are again very different from modern houses so standard units often won't fit - so you either have spacing panels or, as I did get a custom kitchen made - great but pricy.
Roofs are an expensive issue if there are concerns. So you need to know how sound it is and how much "life" it has left in it.
All that said, they are wonderful places to live. The walls are really thick and sound insulation between rooms is great.
We have old big beams that look stunning and massive inglenook fireplaces that you could actually imagine Santa using!
Our energy bills are reasonable - but that's after all those new double glazed windows and having the loft properly insulated. Before that they were very large.
So back to my first point - get a great survey and then quotes for any works before you finalise any offer. You really need to understand if you can cover these overheads and appreciate the word "custom" will be one you'll end up using a lot.
