When applying for a loan, lenders like myself will need to look at several different things if you are trying to prequalify for a loan.
1) Proof of income for each person that will be on the mortgage which can be demonstrated through: one month of pay stubs, previous year's W-2 forms and tax returns, official documentation to demonstrate other forms of income (alimony, child support, etc.), and two year's tax returns if self-employed (all schedules, all pages)
2) Credit Report which they will pull
3) Employment History
4) Personal assets such as: Recent balances and statements for bank accounts, most recent account statement demonstrating market value of any investments (stocks, bonds or certificates of deposit), documentation showing interest in retirement funds, face amount and cash value of life insurance policies, value of significant pieces of personal property, debt information, the balances and account numbers of your current loans and debts, including car loans, credit card balances and any other loans you may have.
I would suggest talking to a lender and checking out what they can do for you. If you have any other questions or need a loan please contact me through the information on my profile page! Hope this helps and good luck!
