One common mistake among first-timers and repeat buyers alike is accepting the first mortgage that's offered. A seemingly small difference in rates can save you thousands of dollars over the course of a 30-year mortgage, and as long as all of your mortgage applications take place within a short time period, the additional inquiries won't have an adverse effect on your credit score.
The programs vary in what they can offer. In some cases direct financial assistance may be provided to help you pay your mortgage for a short period of time. Payment plans or reduced monthly payments may be offered. However most of the government programs and non-profit organizations will help facilitate some form of loan modification to qualified homeowners. This will provide families time to get back on track by ideally lowering their monthly payment, reducing interest rates or waiving fees.
