I've posted on property too but thought maybe I could get some opinions here as well.... Apologies for such a long post but some background seems necessary as to not drip feed. Our vendors have been seriously hardwork through out the entire process. We live in a small town where everyone knows everyone at least indirectly. They chose a online estate agency who were stringing along the process of us putting in an offer so we ended up contacting the vendor directly. Turned out the agency were lying to the vendor too and they decided to cut them out. So from that stage of offer being accepted we have had no agent.
They are purchasing a vacant flat which is part of an estate, and is literally round the corner from the house we have brought from them.
Due to several delays with the top of the chain we eventually insisted they break the chain or we would pull out. We had been ready to exchange for 4 months by now and it was delay after delay with their purchase which we know via our solicitor on many occasions they were downplaying or outright lying about.
They finally broke chain and we exchanged before Christmas (22/12) with completion date for 6/1. We arranged to collect the keys at 1pm (a time they suggested). I understood that they were initially looking to move into their new purchase early and 'rent' it from their vendor until that purchase was completed. Therefore we assumed as they wouldn't be waiting on their keys that day it should be quite a smooth process.
However they didn't leave until 3 pm and have left 4 van loads of possessions and rubbish in the house and garden. The house was also completely filthy (think uncleaned loo, food in the sink...)
We have spent hours cleaning and packing the remainder of their stuff before we could start to move our own. Fortunately we are moving from a rented place so have the whole weekend. After several requests to come and pick up stuff first thing this morning, only one of the vendors arrived around midday. He is unwell and was unable physically to move items. So we loaded his van for him on 3 occasions and then moved last van load onto street in front of house to allow space for our items. When he returned we offered to load van again for him but he angrily announced he was taking no more of the furniture and we would need to dispose of it. Needless to say none of these items were on the fixtures listing to remain.
So now we have a van loads worth of rubbish and furniture outside of the house to dispose of...
We have now changed the keys as we don't trust the vendors at all and feel they may well have a spare set.
Now here's the point I guess... they've left a motor bike in our shed at the back of the garden. I fully expect they will want to come and pick it up as they've mentioned it several times. We gave them ample opportunity today but they didn't take it on any of the trips back. We feel like if they're willing to blatantly leave all of their old crap and point blank refuse to collect it then they can leave the motor bike too? We can't really stand off with them over the rubbish as it's literally in the street and we will need to move it. However I don't see why they should have the bike!
Am I being petty and angry? Is it worth the fued (they have moved very nearby and it's a small town - not that it seems to deter them from screwing us 
)? Any ideas on the legal standpoint?
Also they informed us today that they have moved into their new flat but not informed their vendor and they are not due to complete for another week. So they are basically squatting. I know they got the keys from the estate agents in order to have plumber in so I can only imagine they either intentionally left place unlocked so they could have access or they have had keys cut. Wondering whether we should do something with that information?!
