Let me just state this - breeding loans should not be entered into lightly. Every little bit needs to be spelled out - including replacement value of her snake, if it were to die in your care and how long you have to pay that to her.
Breeder loans CAN work, but I've seen a lot of friendships ruined over breeder loans and mis-understandings.
With the price of albino's these days - it probably would be simpler for both of you to save your money to buy your own albino's.
