Able was the owner of Blackacre, an undeveloped city lot. Able and Baker executed a written document in which Able agreed to sell Blackacre to Baker and Baker agreed to buy Blackacre from Able for $100,000; the document did not provide for an earnest money down payment. Able recorded the document, as authorized by statute. Able orally gave Baker permission to park his car on Blackacre without charge prior to the closing. Thereafter, Baker frequently parked his car on Blackacre. Another property came on the market that Baker wanted more than Blackacre. Baker decided to try to escape any obligation to Able. Baker had been told that contracts for the purchase and sale of real property require consideration and concluded that because he had made no earnest money down payment, he could refuse to close and not be liable. Baker notified Able of his intention not to close and, in fact, did refuse to close on the date set for the closing. Able brought an appropriate action to compel specific performance by Baker. If Able wins, it will be because 
Baker's use of Blackacre for parking constitutes part performance. general contract rules regarding consideration apply to real estate contracts. the doctrine of equitable conversion applies. the document was recorded.
