I'm currently working full time, and just don't want to have that extra stress.  

@Kyle ReynoldsWouldn’t even stress about it.

This is why I stress the unbelievable importance of a great broker, and not for the reasons most think.There is often times a grave misconception about what I do.

There are a lot of smart people out there that lost a lot of money along the way and dealt with a lot of stress.

It'll provide him with long term passive income, maintenance free living and a financial peace of mind.If you do get it, since it is owner financed (or will be), negotiate at least a price of 80-90% ARV, so just in case anything happens, you already have built in equity to go in and fix this place up with.It can be a HUGE win win for the both of you, just be sure to stress all the benefits to him about it.ALSO, can you charge enough rent (for your area) to make sense?

I told her I would drop the price 5-10k if they really wanted it now, and save myself a lot of stress and long weekends finishing it myself.

But...in the real world of emotions, anxiety, stress... some people sleep better at night by paying down their properties as much as possible. 

So you could close within the 3-year window, potentially keep the current tenant in place(if desired), and avoid stressing about the fine IRS line you're otherwise talking about walking. 

The reason I mentioned that is you don't want to pay two mortgages (or rents) as this can be stressful and doing this planning ahead of time will reduce your chances of failing. 

So yes it is someone elses risk but its the buyers credit and stress levels..
