Property purchase proof

[dolly_jiten]

Hi,

My dad has recently purchased a shop in India but the agreement will not be ready before end of May or June. The only proof he has is the Receipt for initial deposit. Would that be enough to show as a proof of the prospect to start business? Basically my mom is going for her visitor visa interview end of Apr and wants to show that my dad cannot come coz he is starting a new business. To prove that what is the best document to show in this situation where the purchase is not yet complete?

Also, can they show it in the affidavit of financial assets?

Please help.

Thanks
