Hi Dotpiper,

What you are proposing is quite reasonable and you can do just what you are suggesting. You would do well to get some one on one assistance however to ensure that you are entering into an agreement with someone who has the capacity to pay you and can get a home loan to complete the transaction at the end of the day.

You also need to set the arrangement up so that all your what-ifs are covered…such as -what if they lose their job, what if you decide you need to complete earlier, what if they change their mind, what if they cant get a loan in four years etc.

Wraps are a great solution for you, and for a buyer who cant qualify for bank finance right now, but just do your due diligence first or get some hand holding from an expert such as a vendor finance consultant with a Credit licence to make sure you aren't making any fundamental errors. 

Good luck with it.
