How severely would inflation have to rise for it to make sense to burden oneself with a huge mortgage. Many people believe that there is a good chance of hyperinflation in the future. Lets say someone decides to take out a 500,000 dollar mortgage at 5% 30 year fixed right before interest rates start to rise and house prices fall. How much would inflation have to up and over how long a time period for that person to have made a wise choice, compared to renting for ten years after rates go up and prices drop, and buying with cash at a lower price. Not sure how low the price would be though and of course that is a key variable. I am just toying with the idea of housing vs gold. Stash your money in real estate, stash your money in gold? A little bit of both?

A question for the math whizzes

In any decision problem it is important to clarify exactly what are the alternatives under consideration.
If they are "mortgage + house" vs "rent" then yes the case for mortgage is stronger under inflation. Note that the case for buying is stronger if house prices go up, and it is also stronger as rents go up (assuming fixed rate mortgage). If you want to confirm with numbers plug into NY times buy vs rent calculator. Maybe it is true as some have pointed out that wages won't keep up with inflation, but it is difficult to see a kind of inflation where rents not go up as the money supply increases. In fact owners equivalent rent is a key part of the standard inflation definition.
If the alternatives are "buy house with cash" vs "invest same cash in something else" then maybe if you are a very good stock picker you could do better in the market. But it is difficult to see why market index in general should do better than a house generating (or saving) rent. Why would people make more money selling iPhones, cars, or soda than they would from renting out a house?
I would also mention that taxes play a *huge* role when inflation is big. Suppose you have 10% inflation and you have found a good asset that also goes up by 10%, just keeping your real value constant. But then, depending on how well you manage your taxes you may have to pay income tax, capital gains tax, or no tax at all on the 10% "gain". Owning a house is very good from this perspective.

I have read the links you have linked me to and in addition alot of the links that they link to in those blogs. It is all very intriguing and I have to say it seems very likely, if not inevitable. It sounds crazy, but I think everyone also will concede that is is definitley not impossible. So If this is the case, if the dollar is going to be worthless sooner or later, then isn't the entire point of this site and many others, how house prices are outrageously inflated, a moot point? Buy however much you can afford now, make the minimum payment, stock up on food, guns and ammo, and wait for the dollar to collapse? Maybe that is the way to go.

Of course it is a moot point if the dollar goes toast.
I mean dollar is the unit of measurement for not just houses, practically everything in the world. If that collapses, sure we are staring at a true financial armageddon. 2008 would be a child's play compared to that.
woppa says
Well, it depends. The problem with a confidence collapse is you can never tell when it's gonna happen. It can happen a year from now, or may be even a decade from now. It can even be avoided through disciplined fiscal and monetary policy, but is that politically and economically feasible?
Complex dynamic systems are not easy to model, they are totally non-linear. I would say, preparation is critical for general peace of mind.
Taking on debt is not bad if the income stream can support it and the debt is at a reasonable level when compared to disposable income.
The other prepping part you refer to -- some people here will think that's totally crazy. And sure there are tons of places and websites that try to sell their stuff using this whole apocalypse concept.

non recourse is a huge advantage to buying in cali.
Even though FHA demands 3.5% and fairly high MI payment - they also allow the seller to contribute up to 6% toward closing costs (meaning they cover your down payment and bank underwriting fees and maybe new carpet).
I might buy this year for a primary residence, if prices crash much further give house back to Obama after squatting 3 years in it, selling off all the applicances, and moving fence line over 10 feet to give land to the neighbor if he pays me enough $. haha. (that happens)

Wow, people love talking about anything instead of MATH. Here goes...
Assumptions:
Fixed Interest rate of 4.0%
$500,000 loan
20% down
vs.
Renting the same place for $2000/mo
lets look at living in the place for seven years and include Interest, tax, ins, water (something you generally don't have to pay as a renter) and extra maintenance. I assumed int and tax will be fixed (prop 13...) and ins, water and maint are subject to the same inflation as rent.
At what inflation point do these break even?... With these assumptions it takes around 26% inflation to make owning break even in seven years.
Of course I'm using the typical numbers from the little beach community where I live (Summerland, CA).
If you go to someplace like Vegas where you can either rent a nice house for $1750, or buy it for $200,000... With all the same assumptions you can have NEGATIVE 8% inflation and come out ahead by owning.

You're asking the wrong question. Salary inflation is what inflates house prices, not just plain old inflation. Salary inflation is a response to inflation and is therefore lagging. They're not even 1-to-1. If your salary has barely crept up during a state of hyperinflation, you're screwed!
Chart already presented by uomo:

The average salary is down to $49,445. Inflation wasn't negative, was it?
Salary inflation simply devalues your debt, as you get a better income-to-debt ratio. Let's just take the numbers presented by California Equity & Loan. Here's what I got.
Additional assumptions:
- Starting salary is $50,000
- Salary inflation is approx 7% (roughly doubles your salary in 10 years)
After 10 years:
- Starting income-to-debt is $50,000 to $400,000
- Ending income-to-debt is $100,000 to $315,000

Patrick, that is an interesting question. I have been writing some finance programs in Javascript for a class I am teaching. If free time crops up, then I will look at your question.
By the way, the U.S. has never experienced hyperinflation. Using Cagan's definition, hyperinflation is inflation exceeding 50% per month.
Hyperinflation causes many problems, so I restrict myself to five.
(1) Interest rates will also with inflation. If the inflation rate is 600% per year (12*50%), then the interest rates will be slightly higher than this rate. If you have a fixed interest rate loan, then loan balance is reduced to nothing. If you have an adjustable rate loan, then this could be dangerous.
(2) Savers are severely penalized if they keep their savings in that currency. Furthermore, the financial sector would not survive a hyperinflation episode.
(3) People stop using the currency as a medium of exchange. Barter would make a come back. The key is you do not have to buy gold or precious metals. Anything of value becomes a medium of exchange, like bullets, seeds, medicines, cigarettes, bottles of gasoline, etc. Foreign currencies could also become valuable.
(4) Hyperinflation would destroy the U.S. government's budget along with the state's and local governments. (Would people still pay their taxes?) Government will put its survival before its people. I would not be surprised if government would start confiscating the precious metals.
(5) Wages are not likely to keep pace with hyperinflation, so most people will literally be shoved into poverty overnight. The good question would policemen, firemen, soldiers, and medical personnel still report to work? When the Soviet Union collapsed, people still reported to work, even when they were not paid in months. I do not think Americans would do the same.
Vladimir Lenin has a great quote, "The best way to destroy the capitalist system is to debauch the currency."

We banned our citizens from owning gold in April 1933. Soon after that, we defaulted in October 1933. The result was monetary illiquidity that prolonged the depression that lasted until the end of WWII.
TravellingProfessor says
That should happen BEFORE the event. Also, it was not confiscation per se. People got dollars for their precious metals. In 1933, if you had a safe deposit box, an agent would have to be present before you could open your box. He would then take your metals (if any) and write you a check. Don't fall for any of the intentional misinformation out there.
Now, what have we learned from Weimar, Argentina, etc, etc? Hyperinflation is intense short-term pain, but both countries were back on track immediately after the event.

I don't see inflation "helping" the housing market since I expect in a domestic inflationary environment to see wages not indexed to inflation. Housing prises aren't likely to rise at all just because there is inflation unless wages rise as well.

The fed has held basic inflation to 2% and will maintain this for the foreseeable future.
Also stated the fed will devalue the dollar 33% over 20 years.
Wage inflation ! it's stagnant for 30yrs+.
Interest rates are only going to fall.
Once interest rates are allowed to rise (unlikely) property prices will fall and create more starts.
However, even 1/4 percent raise in rates is equal to $1 Trillion of added cost to the governments own debt.

"The Link to Hyperinflation
At this point, it almost doesn't matter what the 'right' thing to do is. There is no right or wrong anymore. The time for the altruistic decisions was years ago before the US chose a path of dependence.
Today, it is almost impossible to cut spending because the population and economy is dependent on it. Worse, as the effects of spending shrink more spending is needed to maintain the status quo.
Today the US government can borrow at ultra low rates - tomorrow, creditors may withdraw and interest rates may skyrocket. If that were to happen the government could choose to print (more) money to pay for social lubrication and keep the population sanguine for a few more months. It is this sort of trapping that can eventually lead to a hyperinflationary cliff.
While many investors have turned to gold (GLD), silver (SLV) and commodities (DBC) as a potential hedge against currency collapse, there are other ways to potentially protect. Nobody really knows what will work until after the fact, but some investors believe that US stocks (SPY) - particularly ones with pricing power - could fare well. Other US investors might want to consider investing in non-US assets such as the iShares MSCI EAFE Index Fund (EFA).
Personally, I'll stick with gold as my insurance policy against currency"

10 or even 20% annual inflation is not "hyperinflation" according to any actual economist. Hyperinflation is characterized by an economy where you literally can't make any long term financial decisions because things are inflating so fast that there's no real value in currency. You won't be able to take on a mortgage because NOBODY WILL LEND MONEY.
Now, if you want to replace the word with "inflation", it's really simple
1.) Determine monthly mortgage payment.
2.) Make a guess as to how many years you will live in the home.
3.) Calculate the total rental price for that period of time, assuming your target inflation percentage (say, 5%).
3b.) Subtract the rent from mortgage and project investment growth over the period (say, 5%)
4.) Calculate the total cost of the mortgage (+taxes) for that period of time.
4b.) Subtract mortgage interest savings, add maintenance costs.
If 4b. is greater than 3b., it's cheaper to buy.
There are dozens of online calculators to make this equation.
However, and this is a big one: There's a world of difference between renting a home and owning, aside from finances. I can choose to remodel a home, and I can use it as collateral for other low interest debt (much lower than any other form of credit you'll ever get). It's hard to put an equivalent financial value on those things.

It's one advantage, yes.
Being able to use your home as collateral for taking out a loan is a tremendous advantage when you need money for some project. It could be starting a business or paying for an advanced degree. The interest rate you pay on that secured debt is a small fraction of what you pay on the typical unsecured credit lines like credit cards or personal loans.
Just because you don't understand the value of credit doesn't make it a bad idea.
Many people have started businesses using capital borrowed against their homes. It's a perfectly reasonable way to do things.
And, yes, literally "borrowing" your way to prosperity is how virtually everybody who wasn't born into wealth got that way. Every silicon valley tech company borrowed money to get started. Every restaurant chain, every bank, every small business in your community. Very few people have the cash in the bank to start a business. Borrowing with your home as collateral is the single most common method for small business financing, as it's less than half the cost of borrowing against the new business itself (which the bank just treats as unsecured debt).

I agree with the points made about using house debt do to do these things. They have the potential to greatly benefit the borrower, making the amount paltry in the long run. It is one way of doing it. The number of people that ACTUALLY do that with a HELOC is almost insignificant.
With interest rates what they are now, why not just take out business loans? The qualification requirements are higher than those for a HELOC as are interest rates, but in the end, if the business succeeds the amount borrowed still turns out to be paltry. Borrowing against the house like that does still have some possibility of rendering the loan owner into a renter again. I am just not really seeing a sound logical argument for borrowing lots of money to get a house which you then use to borrow more money to MAYBE become more successful. Lots of people have formed start-ups while renting and securing business loans and/or VC money. I'd rather have to walk away from that stuff than my house if things don't work out. If things DO work out, whatever I borrowed for a business loan or in VC won't be that big of a deal because my business will be making me much more than that.

7 years @ 7-10% (SBA loan) vs. 10 years @ 3-4% (HELOC)?
If you have equity in your house, it's MUCH cheaper to use that.
bmwman91 says
Haha, no! The vast majority of businesses fail, and those that succeed frequently struggle to pay back their early loans. There's a whole world of industry between failure and becoming a publicly traded company. The world runs on companies that earn under $1M / year, and to those companies 10% interest is a shit load of money. Many, many companies that are seemingly "successful" wind up failing because they can't repay their debts.
bmwman91 says
Yeah, in the loopy world of silicon valley, sure. In the rest of the world, "VC" isn't even a word that people know. You either borrow the money from your dad or you borrow the money from your house. You can try to borrow the money from the bank, but:
1. They probably won't lend to you.
2. The most they'll lend to you is relatively small.
3. They'll give you what you need, but you'll be paying a minimum of 10%.
Anyway, I'm not suggesting that you buy a house just so that you have the HELOC option, simply that it's an intangible benefit that you'll get if you have equity in your home that you'll never get by renting. A HELOC is the cheapest debt you'll ever be able to get outside of borrowing against your retirement account.

In any case, software engineer/developer is currenty the most lucrative working class profession in the world.
15-20 years ago, companies like Cisco, Sandisk, Rambus, Juniper went from zero to hero and back near zero, mostly on the hardware side. An EE was lucrative because a company can go from nothing to billions on the backs of hardware, based mostly on eletrical engineering and related analog/digital scheme.
Currently, companies like Salesforce, Google, Facebook, Youtube, Rovio, Linkedin are zero to hero companies. Instagram got snapped up after 1 years of existance in the billions. It's mostly on the software development side. When Youtube can be valued at 50B in 6-7 years, software developers are underpaid, even at 300K. San Francisco is software development capital in the world.
When I went to school, a simple circuit like the tamaguchi chicken was worth a lot of money. Now, a simple game, Angry birds is worth a lot of money and royalty.
civil engineer is mostly employed by government and/or large engineer firms public or private like Bectel. It is not set up like hardware or software development as you will not see zero to hero based on civil engineering talents.
In any case, the best thing about being a software developer is they are usually the first set of employees. Afterall, you can't have a company if you can't deliver. Meaning if you work for airbnb, square, twitter, etc, the developers got in the earliest and set the technogocal milestones are reached and each round of funding values the company even more.

BMW,
A HELOC is by far the cheapest loan available. I have line of credits in 200K, 100K at prime -1%. They are 1.75% net of tax deduction. Intuitively, how can a debt be an asset, but it is an asset not applicable to renters.
Besides starting a business, I can use the cash to pay all cash for another house. In fact, that is what's happening at the field level right now as a cash offer is really financed from another house, which eventually becomes delayed financing anyway.
Starbucks would never become a 40K store monster if all they use was cash flow from operations for new stores. In the early years, they borrowed money to build 100-200 stores a year, once they reached 1000-2000 stores, it was the basis for them to go public, they did and eventually started to build 1000-2000 stores annually to reach where they are total. With public money, their bank loans are cheaper. Debt made it all happen. If it was strictly cash from operations, there is no way they can build 100 stores a year when they they have 100, they can possibly fund 10 a year.

Not really. It's a great profession, but surgeons, dentists, anesthesiologists, trial lawyers, petroleum engineers, quants, and psychologists all get paid much more on average. Software engineering just looks highly paid on paper because it tends to be concentrated in really expensive areas. There are SWEs in places like ohio and arizona making under $75k. No attending surgeon gets paid that poorly.
Software engineering is probably the best paying job you can get without an advanced degree (or even any degree for that matter) with some regularity. You can certainly make plenty of money in a lot of other professions that don't require an advanced degree (like real estate or banking), but it's a lot harder.
The major downside to being a software engineer is that there are only a handful of places where you can live that will allow you to get paid well and actually enjoy the work that you do. A surgeon or lawyer can go anywhere. I'm limited to big coastal cities (and not all of them, either)
