Have a great day :-)  (If I am wrong, and you get sued and go to jail for the rest of your life, by reading this last sentence, you release me of all liability!)  

Assigning a contract simply takes a few sentences to accomplish.

If the title to all or any part of the Property is unmarketable, or is subject to liens, encumbrances, easements, conditions, restrictions or encroachments other than those excepted in the preceding sentence, Seller will be responsible for remedying or removing the title defect or at its election may choose not to cure the title defect in which case the Buyer may waive the title defect and proceed to Closing or may terminate this Agreement in which case any Earnest Money deposit and/or any other funds held in escrow by the Closing Agent shall be refunded to the Buyer.4.

However, that last sentence I dont entirely understand what you're saying.

@Joe VilleneuveCan you elaborate your #3, as well as your very last sentence on "high CF, high maintenance'....

From the calculators I have used, the average I would owe after all expenses etc would be 40k.Your opening sentence is on point.  

Now that sentence may have not made much sense so let me try some examples.

@Michael Plante I am not sure what that first sentence of your last reply means, there may have been a typo. 

Originally posted by @Chase Gibson:The seller is open to owner financing due to not having to pay all of the capital gains tax at once, but rather pay it over the life of the loan to me.I would essentially be leading him to believe that he would be able to pay the taxes over a period of 10 years, and then turn around and force him to pay the taxes in full 6-12 months later when I refinance.Just based on this information here, personally I would say that yes - it is unethical because of exactly what you state in your last sentence.

@Kati Henry Ortiz- interesting  ...this sentence from the site   is a bit concerning "exchange for a share in your home’s future value"  ....there isnt  enough  info  to make a  statement ?
