Credit Union Loan

I have a chance to buy a house for 50,000...My only option for a loan is through the credit union,i have already been to speak to them and they have told me they would have to take it to the board, but going by my credit history with them it should not be a problem..has anyone ever done this before?..I work full-time as a farmer so i recieve farm assist..The house i am going to buy is my (future) mother in laws,she wants something smaller as she finds it hard to mantain the house she is in, so we have found an apartment for her close by that we are going to buy for her,in return she is going to give us the house

No reason why you shouldn't do it this way, the credit union are often the only option for small mortgages like this, provided you are sure you can afford it and won't be back here complaining that the credit union should never have given you the money!
