Hello again, BTR. I'm certainly not trying to talk you into anything, but just to clarify by way of a brief example: If you are in say the 25% tax bracket (there is no 20% bracket) and you were able to properly "reclassify" say $1,000 of what you paid the lady under the imputed interest rules --- to interest expense as opposed to principal --- you would then presumably deduct the full $1,000 on your Schedule F and in doing so would reduce your income tax bill by $250 (and perhaps reduce self employment tax as well). By treating all the amounts paid to her as principal, i.e. land cost, you get no current tax deduction or benefit, but IF you were to in some later year sell the place then of course your tax basis would include all the amounts paid to the lady and, using the current tax law and rates, would yield a 15% tax benefit. By deducting the "imputed interest" as per my example you would get a 25% tax benefit NOW rather than the possibility of a 15% tax benefit in a land sale years from now (or possibly no future tax benefit, if you die while still owning the land). So, I guess I would conclude that it would take a pretty unusual set of circumstances for a taxpayer to be worse off by deducting imputed interest. I'll admit that it is a little bit of a pain in the butt for accountants to make the computation of imputed interest when the sales contract does not provide for adequate interest, but that's what we get paid for. ;-)
But enough of this tax talk from me. Congratulations on getting your land paid for over such a short period time (about 5 years I believe it was) and I hope that you will enjoy your place all the more now that you own it free and clear. Best of luck to you. AZ
