Searching for 2 years, is house a nightmare?

[LawdAMercy]

After a very long search we found a suitable house in our town, great! But now wondering if we may need to pull out and lose the money we’ve spent so far.

Biggest issue is a willow tree about 3m away from back wall of the extension. There are no cracks, signs of heave and I thought we’d just get rid of the tree and be ok, but now wondering if that’s a high risk strategy.

Looks like there may not be a building completion cert to the extension, maybe didn’t even have planning permission, waiting to see.

Also it needs a new boiler/cylinder/money spend on electrics, more than we thought.

On the plus side it’s a good size for us, everything else we can afford was too small and we need extra space. Moving to cheaper area means long commute and crap schools.

Not sure what to do?! Plough money into doing extra soil surveys, tree surgeon assessments etc in the hope it’s ok or just walk away now

Do you have the money? That’s the key.

How big is the tree? Also depends on soil type.
That tree is currently sucking up water from the surrounding soil, cut down the tree you'll have more water and then shrinkage as the roots die, which could cause subsidence. If the tree isn't too large then keeping it under control size wise is potentially a better strategy.
How long has the extension been there? If a long time and no issues then I would be a lot less concerned. But if the tree is huge and the extension relatively new then it's be a bit more worried.

All sounds not too bad. You have to take a risk and jump at some point. Otherwise you're in limbo desperately unhappy. Good luck its soo hard.

I guess I need to wait and get more info. Wondering if no building gets very would make it hard to sell on in future? Hard to say how large the tree is as having measured, I’ll add a pic:

Update @Lambsydaisy Turns out the extension is older than I thought - built in 1991. According to a tree surgeon who visited, the willows probably 20 years old and had some branches removed a couple of years ago, so maybe this is the best route to go down…

Then I'd probably take the risk and just keep the tree under control size wise, or even reduce it a bit. Providing I loved the house and location!
