Dealer Status and Installment Sales for Mobile Homes

[Tim Silvers]

Does anyone know if mobile homes on leased land (no parcel) and seller-financed would be eligible for installment method reporting since they are (i) personal not real property, (ii) the notes cannot be considered as cash equivalent and are generally not marketable (no established secondary market), (iii) have a high rate of default/repossession and thus may effectively crumble one of the pillars of revenue recognition?
Example: buy-here-pay-here car lots as mentioned in post from a CPA in this thread.

Here is a tax court case involving mobile homes (with parceled land) in which the sellers used the installment method: Tax Court Decides Reporting Methods for Mobile Home, Land Sales

The outcome does not seem to be a slam-dunk to me, but maybe I'm just interpreting it wrong.
