Looking at a property

[Lawrence L.]

Goodmorning. Looking at a 2 fam semi attached in NYC near Yankee Stadium good shape Sq ft 4,167 plus a two car garage. Would like to change to 4 family, but would have to make 1 apt handicap accesible. Comps in the area are $164-$182 a sq ft.
What I would like to know does it make sense to change to a 4 fam. cost wise because I have to make it handicap accesible. Rents will be $1200 a month.
Enclosed is my numbers
