1) If the owner wants to keep the house, he may want to apply for a loan modification and get his rates and payments lower and within the range he can afford if the bank agrees to the modification
2) The owner can also make the payments to catch up and keep his mortgage current
3) if the owner has no choice, he can also try to sell this as a short sale --- and when it is listed for sale, that's when you can view it. Credit-wise, it is better for the owner to sell it as a short sale instead of letting it go to foreclosure which will affect his credit score more adversely.
4) the owner could give it back to the bank via deed in lieu of foreclosure or
5) file for bankruptcy
But until it is offered for sale, there are no viewings.
