Using HELOC as the down payment for multiplex

[Thushara Gunasinghe]

I have about 150K in my HELOC and planing on using as my down payment for multiplex. My Concern is I may not be able to pay mortgage and HELOC from cash flow which is going to be very low due to price of houses in my market. I really appreciate very experienced community can help me to understand the best way to invest for my multiplex.

Thanks

Thushara.
