TD Bank:OVERPRICED AND OVERBUILT: CANADIAN HOUSING

依勒特

During Canada’s “Housing Boom”, which ran roughly
  h. G% z1 o/ V: _0 ^( pfrom 2002 to 2008, unsustainable price increases drove
unsustainable levels of building. Our view is that house
prices exceeded the value of housing that was justified by
fundamentals by approximately 9% nationwide. This
overpricing compelled a level of residential construction
that exceeded its fundamental-justified level by approximately
12%, an excess that was exaggerated in the past

By “overpricing” we mean that prices detached from

& t; X; x( N+ a+ n8 `both a cyclical downturn and a return of house prices

( I: e7 v1 \! T) [7 FWe consider “overbuilding” of two forms: “demanddriven”

that this demand cannot be sustained; and “supply-driven”
# u6 O' t1 _5 }) w1 n0 @where builders accumulate excessive inventories. Although
4 O0 h. n9 t; dthere is evidence of both types, we contend that Canada’s
“overbuilding” was mainly of the first type, where
- [% T/ Y. i. o) {; Y2 Nhomebuyers pushed homebuilding to an unsustainable pitch
that is now being rapidly reined in.
While most markets won’t face U.S.-style overhangs,
' m+ J- X: J! g1 P, x8 h  h1 l: Othe construction of too many new homes over the boom
" Z5 W$ ~, L9 O( ^  pmeans a deepened slump. This overbuilding will likely weigh
& O# i9 i7 v: b: l6 M. I+ uon markets over the next few years. Even as Canada recovers
from the cyclical downturn, house price growth will
remain choppy and new residential construction will be
: i( j7 x* P" Y4 Gdampened, owing to this structural weakness. Construction
is now undershooting fundamentals and we expect this

125,000 starts over 2009 with a trough around 115,000 units
in the fourth quarter.
To quantify the degree of overpricing and overbuilding,
we first develop an empirical model, based on long-run
7 Q4 I! a8 [' A; ~% s4 R2 o  m1 Nfundamentals of house prices and housing starts in each
" W# r. D9 K+ Q  Y1 L  sprovince. Affordability is the key concept behind home
values since house prices should track incomes over the
long-run. Since homebuilders build to meet demand, we
regard housing prices and household formation as the drivers
of residential construction.
6 [, J/ e/ w( p: x; w. `) J5 LTo examine the degree of overbuilding, we employ a
" h! {, ]$ M8 M: }3 t. H“counter-factual,” asking what level of residential construction
4 ?" m" v! b1 a9 t( uwould have occurred if housing had been priced
optimally. We find that actual homebuilding exceeded this
7 d# c7 @2 ]+ H2 }fundamental-justified level by about 12%. Although new
units were being absorbed, homebuyers simply bought too

. W( Q: ^& C6 B" lRegionally, we see the greatest strains on the Prairies,
where housing demand will further contract under waning
$ j+ P5 F# K* l9 J& M/ k7 `population inflows. Saskatoon, Calgary and Edmonton are
already witnessing surges in their unsold new homes at the
very time that the resale market has swung into strong
buyers’ territory. Homebuilding in the Atlantic provinces
has been relatively balanced but, while not plagued by structural
weakness, will be singed by the downturn nonetheless.
Québec shows signs of strain – especially given the
strange accumulation of unabsorbed multiples on l’Île de
9 R5 p8 l: i/ ~Montréal – but recent building has been relatively balanced,

cyclical downturn, the degree of structural weakness appears
limited – with the important exception of the Toronto
condo market. Both in Toronto and Vancouver, historically
high levels of apartment-style units presently under
construction mean that record numbers of condos will
reach completion during 2009. If absorption rates fall, as
cyclical factors would indicate, condo inventories could
spike severely – particularly in Vancouver. However, while
