@Michael Hicks The appraiser would most likely mark them "as subject to" be completed prior to closing. 

Mark hi,Thank you so much for replying.  

Hello BP members,My name is Anthony and I live in Greenville, SC.  

yes get a labor price and material most people that do deck can give you a sq foot price if you get the supplies your self you will take some of the mark up  on the deck and just be paying for labor only if you are not afraid to take the debris away your self you can save some more. by doing this you can save about 20%that 1400 not bad for one day all you did was order the supples and have it deliver to the job site and at the end of the job remove the debris your self .

@Mark Schneider, Tacking multiple parties is not hard in theory, each person's period of possession is added to the next possessor's, -but proving all the elements of adverse possession for each party gets tricky.  

If the buyer defaults or causes damage, you need to be a named insured on the policy.Your insurance agent should be able to make this happen - Mark

This year marks my first year as a real estate investor.

@Mark-yes I have considered owner financing as an option, I just wanted some opinions on this offer.
