Magnolia hate root disturbance, and if any of the plants you've mentioned have been in situ for longer than 3 years, they'll be difficult to move. Or you could pay thousands to a specialist company who'll come in with special equipment, take out a massive root ball using a crane and other stuff, and transport them for you to your new home. You'd probably need a mortgage to pay the costs of that ...

And you have to specify to the prospective purchasers which plants you intend to take, normally the house and garden are sold "as seen" which includes the plants unless any are specifically excluded.

If you are going to try and take the trees with you then now is the last time before June that you should. Bear in mind what Bamboo has said about Magnolia not liking their roots disturbed (it may kill the tree).

If you pot the trees with a large root ball, keep them watered and feed then you stand a good chance. They will be seen as movable items and not fixed ones, so you can legally take them (this should be before concluded missives).

We don't have concluded missives in England and Wales, so assuming that Gonzo is in one of those countries, the plants he/she wants to take should be potted up (thereby becoming moveable items) or specifically excluded in writing from the contract before contracts are exchanged.

Yes, regarding the Magnolia I can also concur and say don't bother moving it if its been in more than a couple of years. A known customer of mine asked me a year ago about moving one to which I suggested not to. She came in a few days ago to say that the buds looked dry and were not swelling. I asked her if she had moved it to which she replied only a few feet away. I took a deep breath and stifled what I wanted to say and replied two feet or a thousand miles is the same thing to a Magnolia!

Ha ha, Fractal, 10 out of 10 for self control. I must admit, I'm beginning to understand how frustrating it must be for GPs when their patients come in with a problem and then completely ignore the doc's advice (I'm guilty of that myself, don't trust my GP)

get a new gp bamboo x .

Oh if only, Noseypotter - I seem to live in some sort of parallel universe in my little Lane - no doctor will take me on their books apart from the useless, ineffectual, untrustworthy idiot I'm stuck with right now because they say I'm 'out of their area', I guess its a result of being surrounded by fields which means their areas stop short before my Lane.

Golly, Bamboo,
I thought you lived in the middle of London!

i like it bamboo . i got some of that some years back . i worked making dartboards and cut myself fairly deeply so needed some first aid . i went to the local doctors and they said they couldnt give me some first aid even just to get to my practis so i purpasfully just sat there and bled on there floor till they repented . i dont know what you can do im afraid bamboo short of waitiong for your gp and knocking him of lol .

Ha ha, I find ways round it most of the time, Noseypotter, I just see the Head nurse practitioner instead.
Pennyfarthing, I live in West London, but in a flood area, so we have unbuilt on fields as part of the flood plain/defences - the A40's less than 10 minutes walk behind me though, so not a rural location as such.

Ohh! I see!
