Looking at the area, you are actually 4.94km from the telephone exchange and this is STRAIGHT LINE distance. That is a huge distance and far far higher than most households. As a reference most that I check are usually under 2km. The actual line length is likely to be a lot lot longer as it will not go in a straight line, often going around parks, airports, fields, roads etc and not taking the fastest route. It could easily be double this distance.
You often find that the lines were put down in whatever way was the easiest as back in the day there was no need to have short line (voice worked with long cabling). So often cabling goes further away from the exchange & then loops back on itself.
At this distance it would not surprise me if you couldn't get broadband at all. I would ensure with the current tenants that they have a working and reliable connection. It could very well be that at this distance it's very intermittent. If theirs is fine then you know it'll at least work albeit slow.
It would also not shock me if the speeds were lower than 1Mbps. Perhaps as slow as 512kbps. It would be worth doing a speedtest on the peoples connection who live there already.
Looking at the post code some properties do have fibre services. If you provided the exact house number I could investigate far better.
At these lengths you very often find BT quote a working speed, an engineer comes out and says the cabling is actually too long. No broadband... So definitely check the current tenants connection works.
