I think what TS meant is the SPA is marked up at a higher price in order for him to obtain a loan. In fact there is an actual purchase price agreed upon by the seller and buyer at a lower price compared to the written value on the spa.

Today's reality, usually the purchaser will obtain an offer from bank before deciding to mark up an SPA. So, I'll assume the Offer Letter is obtained before the execution of SPA. Usually inside the SPA, it will written the submission of SPA at what value.
