It's not so easy to establish the fair market value of something that never goes on the market.

True, but I don't think that lodging is "something that never goes on the market". In this example, the mortgage or rental payments for an equivalent property would be pretty straightforward to determine.

[thaumasiotes]

I disagree. Lodging goes on the market all the time, but its market value is highly specific. There is no equivalent property to compare the corporate housing to.

What do you mean? Housing appraisals are done all the time based on finding comparable homes.
