Complex problems have easy, simple to understand, wrong answers. CMHC insures banks for lending risk, and thus provides low low interest rates for home buyers or apartment building owners to provide affordable housing in Canada. It is a crown corporation, thus not designed to take risks, but insure them. Thus, conservative underwriting guidelines with expenses that are reasonable, vacancies that are reasonable, rents that are a reflection of sustainable market rents and CAP rates that are conservative. Thus, lower LTVs of perhaps 75% or lower.
