How do i get preapproved for a mortgage?

You can do either. Some lenders have an online application, some in person and some can do it over the phone. Documents needed are usually
1) ID
2) 2 most recent pay stubs
3) 2 most recent years of W2s or Tax Returns (Self Employed)
4)2 Most recent bank statements

Hi Andrew. I personally suggest finding a local lender. Perhaps someone that a friend or family member used. In my area, sellers and listing agents like to see local lenders involved in the sale. Find a lender who is familiar with your local taxes and other pertinent sale info. Most of the preapproval and application process can be done online. They will need initial information such as income, credit card bills, car loans, rent payments, school loans, bank account balances, etc. Best of luck with your purchase!
