Purchasing second real estate for cash flow investment

[Kevin Lee]

 My wife and I currently owns a single family home that can sell for 80% above the price we bought it for. It is getting old and I feel renting it would cost to much money to repair. I wanted to buy a quadruplex and rent out each unit. I’m not sure where to start as far as if I should sell this house, invest in the multi family home and live there or should I just invest in one, rent out all rooms and move in to a new house? I am new at investing in real estate and currently do not have any rental properties. I only own a single family house.
