Have you ever not met a deadline for giving a loan, if so why? 

Give them a deadline or walk away.

Please note that you are obligated to pay back their 401k (regardless of the performance of your real estate investment).Per the loan offset rules that went into effect with the 2018 Tax and Job Act: if you leave your job and the loan is current at the time you leave your job but then the loan goes into default because you left your job, you will have until your tax return deadline (including any timely filed extension) to make the loan current by depositing the outstanding balance into an IRA (and thereby avoid the taxes and penalties that would otherwise apply).If you are self-employed with no full-time employees & you can rollover the funds, you could set up a Solo 401k, rollover the funds and take a 401k loan from the Solo 401k.

Well, we have no idea what your contract says, but in a standard contract this would not be a legit reason, unless changing lenders at this point would make you miss your financing contingency deadline or delay your closing, which the seller wouldn't have to agree to.

This would be an option if I was unable to find a good property in time to satisfy the 1031 deadlines. 3. 

Set dates and deadlines for when they should be accomplished.Now, what action steps do you need to take to accomplish each objective?

I said that's of course his right and fine to do, but we have a strict deadline to have a new lease executed by Nov 15, otherwise they've been provided notice to vacate by Nov 30.

Or as it gets closer to the deadline he might adjust his demands down to under $50k or other price where it might be attractive enough for a buyer. 2) He doesn't want to negotiate much.

We really want to do this job right, but are not able to so with the deadline codes has given us, and the weather mother nature is throwing at us.

My questions is; Should I proceed with the tight deadline & somewhat scary but beneficial 1031 Exchange?
