two homes on one lot

[Kyle Fitzpatrick]

I recently got under contract a property with two houses on one lot. This may sound like a stupid question but when you purchase a parcel how do you know what all is included on it? Is it based on the dimensions of the lot or what? The question sounds ignorant but in the due diligence process specifically or at the title company etc. At what part do you actually realize what all is on the property.
