Hi Duncan, Yes you can negotiate during the due diligence stage and you can try to negotiate at any point in the sale process until close.If you end up not being able to move forward during your due diligence, your earnest money deposit should actually be fully refunded to you, provided you put in the contract that your offer is contingent on your ability to do your due diligence.There were several deals I worked on where additional repairs were found during our due diligence that necessitated negotiation.What we did was thoroughly explain to the seller the impact of the additional expense and then offer them the options of moving forward at a lower purchase price, or working out terms at the same price (owner financing/sub2/something else), or cancelling the agreement.Usually, the seller would choose to move forward at a lower purchase price but we definitely had parties choose to cancel or finance too.If they chose to move forward at a lower purchase price, we'd write up a simple 1-sentence addendum to the original contract stating the new purchase price and have both parties sign.You may want to include a deadline in writing of when the seller must respond by before you move forward with cancellation so you don't lose your EMD.

This may be a simple case of the realtor having insufficient technical understanding.

@Mike Street this is really simple and so far only 1 person touched on it (@Michael Ketchen), but the short version is because your completely disconnected from reality in what your expecting. 

Keep it simple.

Simple formula is you raise say $2 million in equity from 10-40 passive investors.

I presented him prior to June 1 and he shot back that my lease was full of holes while it is a simple residential lease. 

Get to know the investor or private lender needs first.I've done equity and I've done private lender with simple interest.

This is a huge liability on your part, and so simple to do the right thing

Your wrong, plain and simple.

@Kent Santin keep it simple IMO put 20% down on 1.5M worth of property.
