A Lease Doc loan is a loan on a commercial property that is rented out by a third party. The income verification reqiurements are reduced as the loan relies on your rental income and not on your business or personal income.
The interest rate is usually at the same level as a home loan if the loan to valuation ratio is under 70%.
A lease doc loan is a principal and interest loan and the rental income from the property must be at least 1.25 times the repayments.
