Raising the price of a piece of land in return for transferring a government loan to the purchaser

Is it permissible to raise the price of a piece of land when selling it, in return for transferring the vendor’s right to a loan from the real-estate fund to the purchaser? (The real-estate fund is a fund for interest-free loans set up by the government to help anyone who wants to build a private residence). To explain further: if the land is worth, for example, 500,000 when it is not registered with the real-estate fund, then the owner goes and applies for a loan from the fund, and takes a number to wait his turn. When his turn comes, say three years later, he says to the purchaser: I will sell the land to you for 600,000 and I will give you my turn with the real-estate fund.
