NEED Small Single Story Building for Half-Day Preschool in N. Raleigh

Need a Single Story house or building for a LONG TERM lease/lease purchase in the North Raleigh or Cary areas. MUST be single-story! Rent can be negotiated, but I'd like to stay under $1200.00 per month depending on the size & condition of the space. Building will be used as a licensed, half-day preschool.
