I think that we are appraising the rights of the current owner of record as of the effective date, and if the appraisal is for a purchase, the seller will convey his rights to the real estate to the purchaser.
If the purchaser already has some rights to the real estate, then he will then own the sum of the rights after closing the transaction.
This is where a lot of you are over-analyzing. Appraisals are a product that is purchased by a client. They are judged based upon their intended use.
What is the intended use?
It is to protect the lender and provide basis for a lending decision.
In fact, in this situation, the meeting of minds happened at the excercise of the contract. That is why USPAP requires you to analyze the purchase contract, so you won't make this mistake.
You are appraising the interest that will exist upon closing. Doing anything else will not protect the lender and would be misleading. It is really that simple.
So, Property Economics... you used the term "unencumbered." If the property had a loan against it, that loan would have to be satisfied before it could close. When you appraise it would you appraise as encumbered by the loan? Of course not. What is going to exist at closing is the borrower having a fee simple interest. Appraising anything else in this case would be pointless.
The only way this really gets complicated is because Fannie doesn't allow the use of an HC. Technically, that should probably be done. BUT, appraising the leased fee interest is not what the client wants... they want to know the value of what they will have if they have to take it back... look at the purchase contract.
Also, someone said that the borrower is buying out the leased fee interest. That is really not true. In these lease to purchase deals, the lease ends at the point the purchase option is excercised. Therefore, the borrower is buying fee simple interest... the leased fee interest really does not exist anymore at the point in time the purchase agreement was made.
Technicallity is getting in the way of common sense here. Judge the appraisal on its intended use, as USPAP requires, and you will have no choice but to appraise the fee simple interest.
