Best source of funds is to pay the tuition fee upfront and show that you are rich (include business and investment income and salary of your family). They wont refuse you for the proof of funds.
Tuition fee, I will pay upfront.
Rest is easier said than done. For the business, I am already providing income tax returns for past 3 years. But if I attach bank statements, it is going to back fire. When I applied for my UK visa as the business as my sponsor, I was refused the visa because the bank accounts were running on over-draft - this is normal for a business but the VO didn't consider it and refused me. But at least there is an implied justification that I don't need business' bank statements as they are not sponsoring me.
Investments: My father is into real estate but as I mentioned the source of the funds is the sale of the property. This is the only recent property he has sold. We have no other investment
income.
Considering this, what else can I do to demonstrate we can indeed afford the tuition? In addition, please let me know what you think of what I wrote in bold-text in my previous post.
Father's salary: Not a good way to go by. it is about 200,000 a month but he has to run a house as well so VO will never be satisfied by this.
