So I'm basically trying to explore if i can borrow money in an alternative way than conventional loan.

For investments, you'll likely want a conventional loan for commercial properties.

Also I've heard of some DSCR loans that are not too far off from conventional rates.  

If your partner does a conventional loan, you would sign allowing the mortgage to be recorded, but you do not need to sign as personal guarantee on the NOTE for a conventional loan either!

For a conventional loan, you can borrow UP to what you paid for the property plus closing costs OR 75% of the appraised value which ever is less.  

I financed this deal on a 30yr conventional loan and I put 11,000 down with a 6.625% interest rate.

AAPL is another one  that is just a private organization that teach's folks how to lend their own money or others in states its legal and they have courses and info and a big convention etc and you get to say your certified AAPL lender ..

Conventional Financing How did you add value to the deal?

. #3 - Have finances in order (i.e) is this going to be bought through conventional, cash, HML, etc.

Conventional loan, 20% down non-owner occupied.
