Hello there,
You do not need to present a bank statement showing either a mega grand or overdraft.
Just present your pay slips for the previous 6 months, a letter from your employer showing your income and the job offer letter for your husband.
In your constructed supporting letter you may wish to write:
My husband and I are able to support ourselves and any dependants adequately without resources to public funds. I currently work as ……. With a take home salary of £ …. a month. He will start his job as …… once we return to the UK with a take home salary of £ …. a month.
The respected ECO can not write a refusal based on his imagination or presumption if you provided these documents.
I know a British woman living in the USA with a green card who has got
ILR (not a tiny 2years spouse visa) for her husband through a job offer letter and a prove of accommodation at her parent's house only.
This letter came through a family connection. He even worked elsewhere from day 1. Unfortunately, he did not like to live in the UK and asked her to return to the USA after one year. They did.
It is not the ECO’s business. The ECO is not an investigator. He/she is employed to apply the law only.
Good luck
