At the time she got Bi-lateral knee replacements and was forced to go to work because she couldn’t afford to stay home.

Any financing accomplished becomes a bilateral agreement, I doubt you are aware of that as seems most wholesalers aren't aware, but you cannot assign your financing agreement (or part of your contract) to another buyer without obtaining specific consent of the seller/lender, that is simply uniform law in all states.

Does any one have any experience successfully doing two simultaneous bilateral 1031 exchanges? 

There are plenty of faces that pop up on this forum a lot that say a whole lot of nothing as well.I would say I respect the posters who have a range of experience, have actually done a lot of deals, and also have bilateral opinions that see what may be legitimate and illegitimate about both sides of a topic tend to earn my respect. 

An option is what is called a "unilateral contract" (a typical real estate contract is what's called a "bilateral contract").The difference between a "Uni"lateral contract and a "Bi"lateral contract is just as the words imply:Uni = one = only one party to the contract is obligated.Bi = two = both parties to the contract are obligated.A standard real estate contract is a bilateral contract, which obligates both buyer and seller to perform.

To get that equitable interest, you must exercise the option and sign the attached purchase & sale agreement to create a bilateral obligation.

I've discussed this with several accountants and also consulted with one of the top cross boarder tax specialists in Toronto.Steven's response is correct; due to similarities in law, tax policies and bilateral treaties, there is little if any double taxation when Canadians invest in the US.

You don't need an MBA, but you do need to learn really how the business world operates, it's not how most people think, at least on here.Then pick your industry, here, you have chosen RE.Basic knowledge is dry, unexciting, when you read it it's hard to see where the money is or how in the world does knowing that a legal description "closes" or what a certain deed of conveyance does to make you money.The reason most have problems trying to follow some guru path to wealth is because they don't understand the foundation that the strategy is built on.In basic business law you'll learn what an endorsement is, what an assignment is and the different types of contracts there are (not talking RE contracts I'm speaking of unilateral and bi-lateral contracts).

In a contract it is a bi-lateral agreement, meaning you perform and they perform...

They see it similarly but they're more concerned with is it a Unilateral or Bilateral (if you don't know, its Unilateral).
