Open question: Judicial decline explanation on a house?

So my husband and I had to move from the condition, which is received suitable it a job losing and another in another condition. We wrote a hardness letter to the bank, gave them financial information etc., therefore we could prepare something, therefore we could hold our house in California back. At this moment we have a tenant in him 1,400 one month paying, but our house payments are 1622 plus 75 for the property manager. My husband forms now 2700 a month and we must 900 in the rent here pay. Anyway my question is, our bank refused to us change at our loan. We have to drop back already because we would help hoping them us out were, but we not really us to carry out to be able to hold it. How long does a judicial decline explanation take? What is the process? Does it remain how long on our credit informations? Thanks
