Thank you for your query. I am a Solicitor-Advocate in the UK and will be assisting you with your question today.
Unfortunately, your question is not a straight forward one and one which cannot definitively be answered without seeing the security documents in respect of the loan.
On the face of it, you may have a Bridging Loan with Development Finance. Such a loan would have a monitoring surveyor appointed who would make regular visits to the property and report back to the lender.
If you feel that the Receivers have not acted correctly, you would have the right to complain against them. You will first need to find out which professional body they are a member of. Details of how to complain can be found at the following link: https://www.insolvencydirect.bis.gov.uk/ExternalOnlineForms/InsolvencyPractitionerComplaint.aspx
Lastly, I would suggest you look into whether you were mis-sold the loan ion the first place by your Broker or financial advisor.
I am sorry if this was not the answer you were expecting.
If you have any further questions, please do not hesitate to ask.
