Foundation problem - can I sell as a tear-down?

My house in the east end of Toronto is in need of several upgrades, and recently I noticed a bowing / leaning-outward of the poured-concrete foundation over a stretch along one side. Suddenly foundation repair has become the top priority, and all other upgrades will be put off - probably into the far future - if we can even afford to get the foundation work done.

I know that builders are buying "tear-down" properties in my area - there's plenty of such construction happening around here. I'm wondering if it's likely that they would consider buying a place that needs foundation repair (or a new foundation) or if that makes it cost-prohibitive for them.

I'm wondering if the place is likely to sell as-is, or if foundation repair should be effected first. Even with that repair done, the rest of the house will still need some work.

We were hoping to sell the house and move within the next year or two anyhow, after some updates, and now feel like this might be the time to walk away. The location is quite good, and houses around here are rarely on the market for more than a week.
