It all depends. There are situations like this all over the place. I have seen soem homes foreclosed on in months and others take years. It depends on the bank, the home owner, and type of loan that they have.
The biggest factor is the home owner. They can delay the process of a foreclosure for an extended period of time. However; if the homes are abondoned then they probably have no desire to work with the banks to keep them. But there is a chance the banks have foreclosed on them and you are not aware of it. Some banks are sitting on properties right now and not putting them back on the market right away. other banks are foreclosing and then putting the house right on the market in a very short period of time.
I had a next door neighbor that abandoned his house and was letting it go back to the bank. it took the bank seven months after he left to foreclose and another year before they came by and decided to market the house for sale. Another one in my neighborhood took almost two years to foreclose; but the bank took less than 2 months to market the house for sale.
There is no clear cut time frame for the banks unfortuantely to foreclose and sell the homes....
