Key house finding terms

[Paul Scalcione Jr]

I've been educating myself a lot lately and my girlfriend and I are searching the housing market countless times everyday. Any recommendations as to any "key words" I could type in to find a house? I've been looking for a multifamily (We'd live in one part and rent the other). I've noticed that some places are listed as multifamily but then others say single family but they're listed as having finished basements set up for apartments.
