The Note/Mortgage for each loan states the dollar amount invested & the % of the total loan by name, for each investor. 

These are business purpose loans so there isn't any sort of red tape when purchasing multiple properties at once or one after another.

What type of loan is this?

What I'm aiming for are turnkey rentals and trying to max out the amount of conventional, lower interest loans. again, the DTI income ratio will be IMPROVED if the property shows cash flow.

It's calculated as the ratio of your total loan amount (loan amount for purchase + loan amount for your rehab) to your total costs (purchase price + rehab budget). 95% is a good target.Avoid application and other upfront/junk fees. 

I know a lender that does 15% down on investment loans.

We also have a PLAN to improve the properties, thus increasing rents and improving cashflow.So, it's important to have a pretty good PLAN about what your goals are!

Our issue is income on papers too low to qualify for the an FHA or traditional loan.

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

DSCR loans programs are like belly buttons...every lender seems to have them.
