Hi, this is my first post here and I was just looking for some information on turning a duplex(that used to be a triplex) back into a triplex. I`m 19 years old and I am looking at my first investment property and came across a duplex that used to be a triplex but was converted back into a duplex. Their is an unfinished basement now (which used to be the third apartment) and the seller is offering $3000 at closing to finish the basement bathroom and kitchen. I am interested in this property but am not too sure how difficult it is too turn a duplex into a legal triplex. Any ideas?
