margin loan as down payment for hard money loan?

[Lauren Holmes]

Hi! I am looking to purchase my 3rd investment property but I am tapped out on cash for a down payment. I do have ~$250k in a stock portfolio and just learned about margin loans. I'm wondering if I can take out a margin loan to borrow a down payment for a hard money loan (my understanding is usually 20% down is needed for a hard money loan). My plan is to find a property that is somewhat distressed/outdated/needs renovated so I can improve the value and then refinance it with the goal to pull out enough money to pay back the margin loan and what's owed on the hard money loan. Does this seem like it could work or am I dreaming? 

PS: my DTI will not allow for any type of 2nd home or investment loan so that's why I think I need to go with hard money

Thanks so much for any insights! :)
