Prospective tenants are asking for financial statements from landlords, hoping to avoid companies that might default on their mortgages and leave tenants at risk of losing the space. Tenants are also more wary of subleasing space, and are tending to flock to buildings with stable owners.

'We have to be more attentive to the finances of our landlords than we’ve ever been to get a sense of their financial stability and ability to service their debt,' said David N. Feldman, a managing partner at the law firm Feldman Weinstein & Smith, a 12,500-square-foot office tenant at 420 Lexington Avenue near Grand Central Terminal that, with a lease expiring in 2011, will soon start looking for office space.
