This survey of empty properties in Birmingham found that nearly
two-thirds of the empty private properties are houses. One in ten
flats or maisonettes.
One in six is above commericial premises.
Over a third of empty properties have five or more rooms, with three
in ten having up to three and one in five four.

Over half the owners rate the present condition of their property good
and nearly a quarter as poor.
This survey also goes into greater detail about the type of property,
how long it has been empty , the reasons for it being empty, reasons
for ownership, problems with ownership and the long term intentions
for the property.

<Hope this helps.>

I found the research undertaken to be useful and for the most part
what I have been seeking to establish.
Thank you.

How would you define a derelict property

A derelect property would be one that was in such bad repair and
condition that it was just a shell and could either be pulled down and
a new property built in its place or a property that was in an
uninhabitable state but could be restored and rebuilt to its original
state
