Check on Craigslist, get a list from a realtor of non owner occupied multi family's in you area and write the owner a letter with your intentions and needs.

However, when I bought my current occupied residence it was listed for 359.

Call tenants that are occupying similar spaces around town and ask them when their lease expires, notify them of your available units. 

Owner occupied loan with no PMI.

It will be owner occupied for 2 years then become an investment property.

Purchase price: $225,000 Cash invested: $7,875 House hack - owner occupied duplex, so currently no positive cash flow What made you interested in investing in this type of deal?

We jumped on one years ago that had such a poor cashflow that 23 potential buyers who went through it didn't even bother to make a single offer. 3 of the units were in rough shape & had been vacant for 3 years, another unit was occupied by the old caretaker guy who lived for free.

(owner-occupying would be prohibited since it's a "personal benefit" to the account owner, correct?) 

If the property is solely tenant occupied you will be looking for a Dwelling/Fire Policy (may be called a Landorrd policy or similar name) or a commercial policy such as a Businessowners or Package polciy.

Owner occupied conventional loan with 3% down.
