purple,
Just keeping it simple:-
In terms of accomodation
Details of suitable accomodation
Mortgage payments that appear in the bank statements.
A letter from the mortgage provider and ideally an appropriate entry from the Land Registry
In terms of finances
Evidence that you can support yourselves without recourse to public funds.
Normally, pay slips for at least the last 3 months(6 months is better)
(P60 if no pay slips available)
Bank statements for at least the last 3 months (6 months is better)
Notes: disproportionate deposits and withdrawals in the bank statements need
to be clearly explained in the sponsor's letter.
Bank statements should not really show overdrawn accounts
Showing evidence of savings will help
I assume that all other docs you supplied are in line with UKBA requirements.
It may be taking some time to process as you submitted quite a lot of financial docs
