Visa help for mother in law

Hi

I'm British citizen and we expecting a baby soon so want to sponsor me mother in law to come in the UK to stay with us for few months.

She has been in the UK in the past but I have have 2 question which need to ask.

1) my bank statement is still on previous address haven't changed it but the address on my pay slip has been changed to new. Does it really matter?

2) I have 2 bed room. Privately rented house and my council also topup little bit towards the rent so is that gonna be any problem?

I have saving account where I have reasonably amount? Can I just show them instead 6 months bank statement.

Please advice.

seems ok to me

no problem

ok
.
but make sure the visitor show strong ties back home which make sure she will return before her visa expires.

I'm on the same boat pls some one advice me on that.

I am attaching the bank statement and payslips ect but my salary don't come into my account which I'm sending.

Is that a problem or payslip and previous p60 will satisfy that.

Thanks

Someone please advice the above.

Cheers
