The earnest money has been deposited, the buyer placed an "As-Is" purchase term in the contract, and the ground work for the development is all but complete (city approvals, complete plans/engineering, permits will be issued within the next week or so, etc.).  

The Buyer can terminate the contract if the issues are not resolved with the Seller (me).There is a termite inspection to occur 7 days after Dec 1.

I was just informed that our flights to work are being terminated.

It's FREE and a lot of people, including tenants searching for a home, come through this site to find what they're looking forScreen and select qualified tenantHost an open house personallyHave application forms ready with requirements, what's going to happen in the screening process, and the qualities you expect from your tenantsAvoid fair housing problemsLease-Up the tenantSet and collect the rentImplement day-to-day operationsHave a handyman you can trust and who will get the job done in a timely mannerGet things done in order to keep your business running smoothly (rent, taxes, mortgage, maintenance, etc.)Know how to renew leases AND how to deliver termination letters and deal with evictionIf they're a good tenant and you're a great landlord, your tenants will have no problem renewing a new lease period with youIf they're not a good tenant and start missing payments and etc use your current relationship with them to reason out a solution.

If you're currently renting can you cut the lease (some leases will let you terminate early due to job loss and if not if you give the landlord as much notice as possible they may work with you and more notice means a better chance landlord can find a replacement tenant so that lease break charges to you are minimized) and move in with relatives or at least a cheaper rental?  

If due diligence is ending and you are undecided it's better to send a letter of termination then let a contingency pass and be in a bad situation having to perform on a contract. 

There is unprecidented growth planned for the city including The Salesforce tower, 181 Frmont, Transbay terminal and 5M projects all of these creating tons of jobs and housing. 

Although in the lease we didn't mention how to terminate the lease early from the tenant's side, I think it is a common sense for them to let us know in advance if they want to leave early.

Cant I terminate the contract between us?

I once went to the heavily barricaded (Clearly post-Terminator I https://youtu.be/kYt2HmAxHL4 ) police department for a property I was doing due diligence on and they were happy to tell me that the subject property 'only' averaged 20 calls a month!
