What's the problem with 1/1's in mutlifamily properties?

[Jon Huber]

So, I am trolling around for property #4. Being that this will be my fourth mortgage (and final mortgage before the guidelines change), I would like it to be an investment property because the guideline restrictions wouldn't apply to my primary. That being said... I am looking at some multiplexes ranging from 3 units to 10 units. I came across an under-performing multiplex, but they were all 1/1's. I understand from an investment standpoint, it is less ideal than 2/1 or 3/1, etc. All of my investor friends and family tell me the quality of tenant is dramatically different and I should not pursue the deal. I agree on the tenant comment, and understand there MAY be high turnover... however... if my aggressive property management company has high standards for the quality of tenant, why do I care if it is a 2/2 or 1/1? If the income generated from the 1/1's make the numbers work (and work well, I might add!), and my PMs assure me that the tenants they place have good credit and great rental history (which they have found me phenomenal tenants for my other properties, so far)... why not pursue it??

I'll open it up to the forum.
