The water leaked through a shared wall into their neighbor's space and repairs are being made.

Your zoning should be ok, but you want to do everything by the book (which can be costly) to percent future insurance claims or injury claims in an unpermitted basement living space. 

When you're responsible for customizing the layout you can get more creative and find extra space a builder missed out on because they wanted to include some type of flex space or amenity room or it just didn't fit their box.

Does their collective business occupy one of the spaces in the building? 

Quote from @Mark Hudson: Jay, can you tell us about Canadian regs and how the consumer has to refinance after 7 to 10 years? 

It’s taking Seller a while to provide the HVAC report but while time passes after due diligence - Flooring cost is way too expensive at the price point they’re asking for 130K + Care of property never took place till decided to sell so I’m not comfortable any longer - Home sits on corner lot on a slight hill with crawl space - Lots of weather changes has caused the home to settle + improper supports needed. 

After 8 years as a director in the kitchen and bath retail space, I'm bringing my positive energy and relationship building to a wholesaling firm covering Los Angeles and San Diego counties (we specialize in single family homes priced between $400-$1.7M).

Adding rooms does create the potential for more conflict but carefully thought-out floorplans, designate wet and dry storage spaces, and provide supplies.

You have lots of other choices in the free and paid space. 

@Mark Munson I 100% agree.
