However, back in 2004-2006 when so many lofts and condos were built/converted, the average 1 bedroom was about 800sf. What this means is that if you have a large 1 bedroom, you can think of converting these into 2 bedrooms later on, or marketing them as potential 2-bedrooms. Permits needed, of course.
The moral of the story? Buy a condo or loft that was built 10 years ago if size matters.
