Good idea to use Margin loan as down payment?

[Divya Sosa]

Although we had saved up about 75K to start out with a rental property but we were also in a middle of starting another business for which we could not get a SBA loan so we had to put majority of our savings into that. I am able to obtain a margin loan from the stock brokerage account i have for about 25-30K with 0% interest and also no specific time limit to pay back. Would it be a good idea to use that as a down payment for my first rental property? My intention is to pay back the margin loan ASAP (within a year or year and a half).
