The word 'testament' is for all practical purposes defunct in English law and wills now deal with both realty and personalty.

In current day terms you probably wouldn't need probate if the estate amounted to less than £5000 (although as Megan points out, you might come across some awkward beggars).

The value of property is the major part of most people's estates today but back in genealogical times relatively few people owned their own homes. In 1918 77% of households in England and Wales rented their homes.
