Question about contracts

[TeAusha Moffett]

So I potentially will contract my first deal but I’m not sure how to do the contract. Her home flooded (we’re in Houston) and she is willing to selling with the contingency that she receives x amount of dollars from her insurance company. I have a realtor contact that is telling me I must use a regular purchase contract as if I’m the one buying it. This makes me nervous, shouldn’t I be using an assignment contract? Can you put contingency’s in an assignment contract?
