You don’t come in with a power frame just because your offer got accepted, you never truly have control but you can have the upper hand especially if you are no emotional on the reactive side.

Personally I admire the way you have expressed your emotions and your ability to control them, the fact that you turned to your parents for a bit of help shows that you are a good business man - you knew how to make the right choices pushing the project forward.

There are strong emotional forces driving this interest, mainly the proximity to our house (12') and the ability to self manage and select who will be occupying it. 

Play an emotional angle with a video or letter to the seller with your offer.  5. 

Some of the best advise I've heard is to take the emotion out of real estate.

When they have 4 kids and medical issues, etc, it becomes an emotional struggle between doing the right thing and doing what is profitable.  

As excited as I am to complete the first transaction, your questions are a good reminder to make a decision based off of the numbers, and not emotion.

If your goal is to get them out do not hesitate or falter to achieve that goal based on the letter of the law.You are in this mess due to having made emotional decisions, major mistake, do not continue down that path.

Don't get emotionally tied to an idea either.

Not emotional - just as an investment.
