You can get pre-qualified for a mortgage, which simply gives you an estimate of how much a lender may be willing to lend based on your income and debts. But as you get closer to buying a home, it’s smart to get a preapproval, where the lender thoroughly examines your finances and confirms in writing how much it's willing to lend you, and under what terms. Having a preapproval letter in hand makes you look much more serious to a seller and can give you an upper hand over buyers who haven’t taken this step.
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.
