Property type listsource criteria

[Julius Dixon]

I'm trying to buy a list on Listsource and I'm stuck at the property type criteria section. I'm trying to find multi unit properties (probably 1-4 units). Do I select "Residential: Multi Family" or SFR? It seems like a lot of people on bigger pockets suggest selecting SFR, but I'm not looking to find a single family home. Does this question make sense or am I misunderstanding something? Also, when I put in the filter for Residential: Multi Family, my list goes down to 0 from 3,900. Another option would be to put in Residential: Apartment, but I'm not sure if that will give me a list of apartment buildings (which I am looking for) or of single units within apartment buildings. This selection takes it from 3,900 to 488.

Thanks!
