It may also be the title company or policy issuer being a pain but there are states where there isn't a specific legal reason why a public filing of the certification of trust would be warranted for a land trust. 

Have the State come in every 5 years to do a thorough multi-family inspection... and when you are justifying state inspector jobs, you can expect to get dinged on something to warrant a re-inspection.

Condotels - these are non warrantable so check with your lender.

But now we know...Here comes the questions:-The tenants signed a lease through April 30 and expect uninterrupted running water (rightfully so) but now that we know the limitations of the well and water does run, but pauses from time to time, are the tenants still warranted a discount after Feb. 2nd?

It just means that the seller only warrants title for the period of their ownership and not before.

Raise rents if warranted and hold on.

That is, IF there are multiple layers.Common sense solution, get multiple (3) quotes from established Roofers locally, but not any of the "big boys" that you may see on TV or hear on the radio even... those charge enough to warrant the high cost of public advertising!

A challenge was getting lenders for non-warrantable condos.

Things like the driveway, or old aluminum windows, I'd simply deal with once the maintenance fund has enough in it to warrant it.

So, doing equity investors will be more likely to pass muster with the lenders than borrowing down payments.To build on @Joe Impagliazzo "warrant-ability" is the more general issue.
