Here are five tips from GoBankingRates.com.
1.Don't confuse prequalification with preapproval.
Getting prequalified means the lender makes a "guesstimate" of how large a loan the potential home buyer may qualify for. By contrast, preapproval means the lender has examined credit reports, incomes and other assets to determine how much the borrowers can afford.
2.Avoid making major changes to your credit behavior leading up to the time you plan to apply for a mortgage. Applying for new credit, such as an auto loan or credit card, can skew your credit score. Infact, CreditCards.com says how much money you owe to lenders is the second-most important factor in qualifying for a loan. It's nearly as important as paying your bills on time.
3.Don't apply for a loan before personally checking your own credit history. Find out your credit score,tally up your outstanding debts and review your past employment history before meeting with a mortgage lender.
4.Check and recheck your application for any typos or "honest mistakes" that may cause a lender to reject your application. Any misinformation you put down on a mortgage application can be readily verified in today's interconnected world.
5.You've probably heard this 100 times before, but don't forget to read the fine print. Hastily applyingfor a sub-par loan typically ends up being a waste of your time.
