Similar to what Patrick stated - most have ITINs and have seen a lot of loans like that and those are sold many times on secondary market. if not I know people who still originate I would say they are tougher to sell on secondary market but there are still buyersRe: jay comment - price of notes has doubled over past five years on many loans - especially defaulted or loans with some hair too them. 

Living in one unit and renting out the others allows you to deduct 75% of expenses like mortgage interest, property taxes, insurance, and shared repairs as rental expenses, while the remaining 25% applies to personal use.

A bank will not give you the $ as you have to show ability to repay the loan. 

Quote from @Vince Scipione: Standard would be an FHA loan for your situation more than likely.

@Nina Erlandson Personally, I have not heard of Obie Insurance.

I assume you’ve got a loan that says you will be living there.

I heard that if you move the personal mortgages to an LLC they could get called and we would want to avoid that3.

Even 600k loan at 10% interest costs $165 a day.

Often, lenders will not act until the differential between current interest rates and the interest rate on the subject loan reaches a certain point.  

Either way, $600 in cash flow should actually help your personal DTI if you go for conventional financing on a primary again.
