Actually I dont really agree with this, if you think of it like this;
Lets say I own a car or smt which is worth more than the minimum funds. I know that I will be selling it in order to fund myself for my immigration plans. Why would you sell it before ITA ? What if you never get it? Isnt it more logical to sell an asset if you are at least at the stage of ITA? Or think of it like this, you know your family will be giving that amount to you for your settlement, why would they send that much money to your account way before ITA for a visa that you may never get?
In both cases I think its not lying if you already have an asset ready for sale, or you know that your family member is going to support you ... I wouldnt be selling anything or asking for any money if I am not even at the ITA stage.... so its easy to explain..... It doesnt matter if that asset is sold 6 months ago or 2 weeks ago, it was owned by that person at the time of Express Entry profile anyway.... so technically they did have the funds...
Thats what I think....
