Jona,
Try not to focus nor rely too much on savings. Yes savings are important, but not as important as have a regular income and a good cash flow.
Please take a look here at the
UKBA Maintenance (funds) page
Basically, the UKBA will be looking at the amount of money left after any regular non-discretionary expenditure (such as rent or mortgage payments, council tax and secured loans etc) Everyone has have different non-discretionary expenditure.(eg payments of Child support would also be considered a key fixed/regular payment)
The application must be supported by evidence that proves the applicant will not require public funds. Generally this takes the form of the sponsor/applicant (or co-sponsor) providing:-
Bank Statements covering at least 3 months (preferably 6 months)
Salary slips for at least the previous 3 months.(preferably 6 months)
The sponsor's (co-sponsor's) employment contract (if the sponsor is not independently wealthy). A letter from the employer will suffice.
The sponsor's (co-sponsor's) most recent P60.
If the sponsor (co-sponsor) is self-employed, owns his own company, or if the sponsor (co-sponsor) is unemployed, then the employment contract and P60
can be substituted with certified copies of the previous 2 years' tax returns accompanied by a notarized version of his/her business accounts.
If the sponsor (co-sponsor) is retired, then a statement from his pension scheme will do.
If there are disproportionate deposits and withdrawals in the bank statements, they must be explained in the sponsor's letter, in fact explain as much as you can about the transactions.
On the questions about what money can be counted for visa application, UKBA will only accept evidence that maintenance is available in the form of
cash funds. Other accounts or financial instruments (such as shares, bonds and pension funds) are not acceptable, regardless of the notice period.
Sorry to say that finances tied up in houses will not be considered
Hope this help you
