Are lenders becoming a let-down?

There is now a significant incidence of mortgage providers claiming they have not seen the necessary documentation for a mortgage to complete. This is despite the fact it has been sent in good time and nothing has been mentioned until the twelfth hour. It is not only paperwork that seems to be causing problems, but also issues surrounding lenders getting confirmation that the title of the property is sufficient security for the loan in question. Lenders need to ensure all of the corners are squared for each and every application, but it seems strange that these problems have never arisen...
