Number of unit question

[Traver Freeman]

If two duplexes and SFH are being sold in one sale, advertised in the listing as 5 units, is that commercial, or is it still residential because it's 3 separate houses? I am watching my market and I noticed a newer listing that's in my price range, but as I'm looking for my first investment, I don't know that commercial is the way I want to go right off the bat.
