The incentive, certainly if not social housing, is to obtain a good rental yield (annual return on investment) and prospect of property price inflation. The disincentives are the locally varying duties of landlords in repair/maintenance and administration — and keynote risks (tenant disputes, damage, neglect, loss of rent, insurance inavailability/disputes, economic slump, increased rate of interest on any mortgage, and negative equity or loss of investment). Net income (yield) and capital growth from letting (renting out) particularly in leveraged buy to let, is subject to idiosyncratic risk, which is considered objectively intensified for a highly leveraged investor limited to a small number of similar profile homes, of narrow rental market appeal in areas lacking economic resilience.
