The rent-buy spread is out of whack for sure.

Yes. Those ratios in the graph are so low they must be comparing dissimilar properties. You have to compare apples vs apples. For example the rent on a 3/2 1500 sq ft SFR in a good neighborhood versus the price of same. For prospective landlords, normal property pricing gives you a gross annual ROI of 10% to 12%. You need this much cash flow to pay for the property manager, taxes, insurance, and maintenance and still have a return better than bonds to compensate for the risk and worry of managing property. I find the misleading suggestion that landlords have never earned over 6% annual gross ROI in the last 48 years absurd in the extreme.

The problem since 2002 has been that rental property purchases became a Ponzi scheme driven by speculative greed. Stupid people bought properties that were "negatively geared". By this I mean that the rental income didn't even cover the costs of holding the property. In extreme cases, the rental income didn't even pay the taxes and insurance, much less provide any return on capital (if purchased with cash) or pay the mortgage (if purchased with debt, which is much more common). The whole business plan devolved into hoping to quickly flip the properties for a capital gain. Well, now the music has stopped.

So when should a renter stop renting and buy? Buying makes sense if one has adequate assets or a secure stable income AND the neighborhood is not deteriorating, AND one plans to live there for several years AND the cost of purchase is less than 120 months rent. These conditions are not met in most parts of the western world at the moment. I am currently renting a 2000 sq ft 4/2 new brick SFR in a good walkable neighborhood of New Zealand for USD 1300/month. If I wanted to buy the house, the price would be 320 months rent. The price needs to fall over 60% before buying makes any economic sense. Of note, this is the exact inverse of the 150% house price appreciation over the last 4 years. The entire easy credit driven property price bubble will be reversed.

The same logic applies to prospective landlords. In New Zealand, risk free six month government bonds pay 7.5%. Bank CDs pay over 9% (although banks can fail). There will be absolutely no reason for investors to purchase rental properties until the annual gross rental income is well over 10% ROI. The nimrod investors sitting on negatively geared properties with sub 4% yields will be unable to unload these albatrosses for what they paid for them. Couldn't happen to nicer people.

My only worry is having to move if the bank forecloses on my Donald Trump wannabe landlord. Then I would get a new rental house from another insolvent fracked borrower/failed flipper landlord, another possible foreclosure, rinse and repeat. Well that is still better than buying and taking a capital loss of USD 75,000 every year for the next four years.

Hey Micro,
Thanks for this clear headed strategy.
A young colleague of mine is now in the unenviable position of deciding whether to risk his entire savings in the purchase of his first house. However his pre approved credit standing of last year no longer qualifies him since this year Michigan real estate is now considered a declining market by lending institutions.
After only a year on the job, producing 20% of the down payment, on top of student loans, is quite a tall order.
I never give financial advice since I can barely manage my own but I can show him your excellent analysis guilt free!

Thanks too to Gail for her incisive forecast.
It takes more than a bit of courage to offer, in uncertain times, specific views of the future.

Nicely put, Microhydro.

However, you are comparing rental yields of less than 4% with NZ bond rates of 7.5%. Let's say you can get 8% at a decent NZ bank. That's today's rate. What's it likely to be in 2012?

Gail is suggesting that banks will become more and more risk adverse, and thus presumablly will also being offering higher interest rates in order to attract cash to shore up reserves.

I recall that in Australia in the early 90s you could get 12% on a term deposit. Suppose those days come around again? If your choice is between 12% interest from a bank or buying a house and then trying to find good tennants in the middle of a depression, you are probably going to want a 12%-15% gross rental yield. Which would suggest house prices at a quarter of today's level.

To those who say it can't happen - look at Japan. A country giving a good impersonation of a market that will stay dead for a generation.

I think you also have the issue of the empty or abandoned homes. I think we are already seeing stories of people taking up residence in them. Poor folks who cannot afford the rent may be able to drop out of the rent-paying system.
