Making an offer on a house that is contingent upon your finding someone to buy it from you is illegal.6.

Make sure you put the contingencies on the sale contract that will let you either renegotiate or back out of the contract if you have to.Also when you put the house under contract, make sure you deliver the contract to a title company or attorney, with the earnest deposit, in order to show that you have a viable and executed sale contract.

I never have a contingency when buying a rehab.

We had mulled around a number a bit and it worked with my estimated financials so we offed 535,000 contingent on financing, I declined roof inspection(done 1.5 years ago when seller purchased 2/3rd life left) and sewer inspection.

You would typically want to have your contractor walk the property with you before you make your offer so you can factor the rehab estimate into your analysis and then you would have an inspection done immediately after you get the property under contract during your contingency period to make sure there's no other issues.

If you have an old lease authorizing attorney fees, and your tenant hooks up with the right contingency attorney, you could be out thousands if you act too fast.Last comment. 

Then someone comes along and makes an all cash offer of $1.3M with no contingencies. 

Jeremy Anan - make sure your contracts have inspection or financing contingencies.

Lucy Tschappler You can have the agent make an offer that isn’t “all cash” and is contingent upon an inspection.

Do you know what contingencies to include in your offer?
