1) An owner of scummy fungus-, rodent- or insect-infested property which they rent (often for a long period up front) after giving said property a superficial spring-clean and repaint to fool the naive and desperate university student seeking accommodation. Can be recognised by the electric heaters trained on new carpet in said property which the naive tenant falsely believes will warm them through the winter, but are actually to retard mould growth until point of rental and will be removed in secret once they pay up and their backs are turned. Once said infestation manifests, the landlord takes the rental money and the deposit (known to cognoscenti as "bye-bye money"), and disappears to a remote holiday resort, nary to be seen or heard from again. Alternately he may come back for rent in shorter-term instalments, well aware that the law cannot touch him or that he has terrorised the tenant too thoroughly for the latter to test said law. Frequently claims to need to clear out tenants for the purposes of having the residences fitted with all mod cons, then merely has the rooms subdivided into cubicles too small to swing a cat in. The landlord is intimately familiar with (1) all his rights, and (2) the departure times for all flights to Andalucia and the Canaries (or equivalent Stateside). Typically much beloved by students past and present, especially those who managed to get official campus accommodation.
2) Any crook or anti-social parasite with a good PR agency, hitmen to silence "begrudgers" and/or the ability to run fast.
You paid five grand for that place for a year and it started raining through the ceiling? What do you EXPECT when dealing with landlords?
The guy at the till didn't like you in his restaurant, so he spiked your coffee. What a landlord!
GB II is the worst landlord I've ever heard of. When thousands of other young Americans were risking everything in Nam he was looping the loop over Lubbock.
