A prequalification is an estimate of the size of mortgage loan you qualify for based on your previous financial history. A prequalification gives you an idea of how much home you can really afford and is a signal to real estate agents and sellers that you are a serious buyer. Furthermore, a prequalification makes the loan application process easier because each process requires you to provide similar information. You may be asked to provide documents such as paystubs, tax returns, etc. to verify your income. In fact, the more information you can provide for your prequalification, the more precise your estimate will be. The best time to begin this process is before you begin searching for a home.
