Hedging your personal assets
No. Such companies don't exist. Derivative instruments have evolved over a period and there is a market place, stock exchange with members / broker with obligations etc clearly laid out and enforceable. If I understand correctly say the house is at 300 K. You would like a option to sell it to someone for 300 K after 6 months. Lets say you are ready to pay a premium of 10K for this option. After 6 months, if the market price is 400 K you would not exercise the option and if the market price of your house is 200 K you would exercise the option and ask the option writer to buy your house for 300 K. There are quite a few challenges, i.e. who will moderate this transaction. How do we arrive that house is valued at 300K. There could be actions taken by you to damage the property and hence its reduction in value, etc. i.e. A stock exchange like market place for house is not there and it may or may not develop in future.
"Being ""long"" - expecting the price to go up to make a profit - is a two step process:  1) buy 2) sell Being ""short"" - expecting the price to go down to make a profit - is a 5 step process:  1) borrow someone else's asset 2) sell their asset on the open market to somebody else a third party 3) pocket the proceeds of the sell for your own account 4) buy an identical asset for a cheaper price 5) return this identical asset to the person that let you borrow their asset if this is successful you keep the difference between 3) and 4)" "One thing I would add to TTT's answer: One of the benefits of using an LLC for your business is right there in the name - ""limited liability"". It provides a level of protection for your personal assets should your business go bankrupt, get sued, and so forth. However, if someone can show that there's no real separation between your LLC's activities and your personal activities, then they can ""pierce the corporate veil"" and go after your personal assets. If this loan is really purely personal and not related to your business activities, you may create a paper trail that can later be used in this way. My advice would be to just avoid the whole thing and make the loan from personal funds. I don't see any upside to doing this out of the LLC funds." Yes, more leverage increases the variance of your individual portfolio (variance of your personal net worth). The simple way to think about it is that if you only own only 50% of your risky assets, then you can own twice as many risky assets. That means they will move around twice as much (in absolute terms). Expected returns and risk (if risk is variance) both go up. If you lend rather than borrow, then you might have only half your net worth in risky assets, and then your expected returns and variation in returns will go down. Note, the practice of using leverage differs from portfolio theory in a couple important ways. "The essence of hedging is to find an investment that performs well under the conditions that you're concerned about. If you're concerned about China stock dropping, then find something that goes up in value if that asset class goes down.  Maybe put options on a Chinese index fund, or selling short one of those funds? Or, if you're already ""in the money"" on your Chinese stock position, set a stop loss: instruct your broker to sell if that stock hits X or lower.  That way you keep some gains or limit your losses.  That involves liquidating your position, but if you've had a nice run-up, it may be time to consider selling if you feel that the prospects are dimming." You could buy debt/notes or other instruments that pay out periodically.  Some examples are  If there is an income stream you can discount the present value and then buy it/own the rights to income stream. Typically you pay a discounted price for the face value and then receive the income stream over time. That's the foundation of Limited Liability.  There is a corporate veil that protects your personal assets from that of your business.  The corporate veil can be pierced if you do certain stuff and thus your personal assets will get effected.  This allows people to start companies and innovate more and take more risks knowing that they could not be personally liable if the business folds. "Note: I am making a USA-assumption here; keep in mind this answer doesn't necessarily apply to all countries (or even states in the USA).  You asked two questions: I'm looking to buy a property. I do not want to take a risk on this   property. Its sole purpose is to provide me with a place to live. How   would I go about hedging against increasing interest rates, to counter   the increasing mortgage costs? To counter increasing interest rates, obtaining a fixed interest rate on a mortgage is the answer, if that's available.  As far as costs for a mortgage, that depends, as mortgages are tied to the value of the property/home.  If you want a place to live, a piece of property, and want to hedge against possible rising interest rates, a fixed mortgage would work for these goals. Ideally I'd like to not lose money on my property, seeing as I will be   borrowing 95% of the property's value. So, I'd like to hedge against   interest rates and falling property prices in order to have a risk   neutral position on my property. Now we have a different issue.  For instance, if someone had opened a fixed mortgage on a home for $500,000, and the housing value plummeted 50% (or more), the person may still have a fixed interest rate protecting the person from higher rates, but that doesn't protect the property value.  In addition to that, if the person needed to move for a job, that person would face a difficult choice: move and sell at a loss, or move and rent and face some complications. Renting is generally a good idea for people who (1) have not determined if they'll be in an area for more than 5-10 years, (2) want the flexibility to move if their living costs rises (which may be an issue if they lose wages), (3) don't want to pay property taxes (varies by state), homeowner's insurance, or maintenance costs, (4) enjoy regular negotiation (something which renters can do before re-signing a lease or looking for a new place to live).  Again, other conditions can apply to people who favor renting, such as someone might enjoy living in one room out of a house rather than a full apartment or a person who likes a ""change of scenes"" and moves from one apartment to another for a fresh perspective, but these are smaller exceptions. But with renting, you have nothing to re-sell and no financial asset so far as a property is concerned (thus why some real estate agents refer to it as ""throwing away money"" which isn't necessarily true, but one should be aware that the money they invest in renting doesn't go into an asset that can be re-sold)." In the case you propose, a taxable windfall, your best hope is to marry someone who has his/her own loss of about the same amount. This advice would work if your gain is a 10 bagger, as you suggest, but not for a lottery. In the dot com bubble, I heard of more than one couple that got married under these conditions. As far as other gains, it would be tough to contrive a situation that would give you such a tax offset without taking on a huge risk, far greater that the $133K in tax you might save.
