How to fund first investment property

[James Bryson]

Recently inherited a 3 bedroom 2 bath house after the passing of my dad. Own the house free abs clear. It's currently rented and generating positive cash flow. But now I'm considering purchasing 1 or 2 town homes in a college town to rent out and trying to decide if I should mortgage the rental home for the down payment on the prospective rental properties or figure some other method of financing the purchase of the other properties.
