BrokerDirectMLS is pure garbage. 

But if you are looking at it from a pure financial position, probably not. 

I definitely would have declined an application with that many tenants, but now they are accepting a rent increase which is pure profit on top of an already cash flowing property.

@Cassidy Burns Was the property a primary residence or purely investment? 

Hard to answer because for the most part, the properties are not bought using pure cash flow. 

Consider that in your overall decision.The reason why I say to start small is because you can get real life experience from managing an SFR and discovering the joys and tribulations of owning one. 

I would go with whichever one I found the better deal on first.In terms of vacancy a 4plex would be better for the economies of scale.Are you planning to house-hack or is this purely an investment?

I feel it has worked out due to pure luck (appreciation wise), even though it has a neutral to slightly -ve cashflow.

I will continue to rent where I am now and this would end up being purely an investment property. 

Is this pure investment or are you living in one side?
