There are many reasons to NOT do this, I advise going back to your land use guy and have him recommend an agent or tax/real estate attorney to discuss better ways to do what you are are trying to do. (Establish a non-recourse loan, reset the tax base, offset or reallocate costs, et al.)
In fact, what's your ultimate objective. I have the feeling--no offense intended--that you may be overcomplicating this.
And did you have legal counsel as you were splitting the acreage? The reason I ask is that you probably violated your lender's due on sale clause when you did that. If you split the acreage, but the mortgage still applies to the two other lots, then you've diminished the lender's equity--its security--protecting the mortgage.
So, see a lawyer for the best way to accomplish what you want.
And, sure, technically it's possible to buy a house from yourself. You could set up an LLC and either (1) transfer the existing house into the LLC, then purchase the LLC, or (2) deed the property from yourself into your LLC. And there are other ways, as well. But, again, I'm concerned that you may be making this more complicated than it really has to be.
So: Consult a real estate attorney.
Hope that helps.
