Survey for selling house?
It depends. If it's just a required document for the closing process, it will likely suffice because it will show the location of the property as well as the location of its boundaries and their dimensions. However, a subdivision plan does not usually show the building foot print or any other physical features on the property.
If your buyer is asking for an SRPR (surveyor's real property report) then the subdivision plan will not suffice. Similarly if you are wanting to offer the greatest amount of transparency (a good strategy to reduce objections and conditions on offers) then look to find a survey plan that shows the buildings (an SRPR).
