All cases are different. Some people take a few months. Some people are not elegible for qualification and may have to wait 1 or 2 years. It depends on your financial picture. Debt. Savings and many variables
The key thing to remember is that YOU are by far the biggest single factor in how long the process takes. Your most recent two years of financial history and current income, savings, obligations etc. will be what determines the length of time it takes for you to get to closing.
Stick with it and never give up, even if there are unexpected bumps in the road. Follow the program guidelines and your counselor’s instructions to the letter and you will reach the closing table in the shortest amount of time possible, no matter how long or short that time frame may be.
