Pay down and heloc equity for new investment or bank rents

[Brian Stillabower]

Hello all:

I am looking to purchase a small apartment complex, up to 10 units.

I am also wanting to set myself up for future investments as well.

Is it best to take the rents and pay down the mortgage, then when ready for the next investment property borrow that equity.

Or bank all the rents and use when ready for next property?

I am wondering from a financial standpoint. Obviously paying down mortgage will save me in interest but ties up the money and isn’t as liquid as money in the bank. Also I would think there are also tax benefits.

Any insight is appreciated.
