It is not very common.
There are different classes of title. Absolute being the best class and most common.
Do you have a solicitor acting for you? Have they advised you on this?
Are you being with a mortgage? The lender may have an issue with the class of title.
You can certainly try to renegotiate the price based on the fact the seller cannot give absolute title.
You can get indemnity insurance to cover the risk. The seller should cover the premium.
Sadly solicitors are not qualified to advise on matters of valuation. It is outside a solicitor's areas of expertise. You would need a surveyor to advise on whether possessory title affects value.
A buyer is always free to attempt a renegotiation on price. The fact the property has been on the market is also an indication that the seller is in a weaker position. Potentially you could secure a better(lower) price.
Do consider indemnity insurance too if you proceed.
Do you have a solicitor?
Have they advised on title?
I can review title and comment for an additional service. If agreeable i will send you an offer via this site, you accept the offer and attach the title to a message via the paperclip icon.
I cannot see why your solicitor cannot comment on title. It has nothing to do with the contract. If there are issues you can bail out earlier rather than later.
The offer is there if you want advice.
Please can I kindly request that you accept /positive rate my assistance otherwise the website will not pay me for assisting you today. Many thanks.
Either. It does not have to be a solicitor. If you are happy doing it you can.
I think via the website or via a message which I have sent.
