On a 1918 electoral list there are abbreviations H, O, HO, R, NM and BP in the 'Qualifications' columns. Can someone translate, please?

I found this page via Google which lists:

Residence (R)
Business premises (B.P)
Occupation (O)
Occupation of husband (H.O)
Naval or military voter (N.M)

Thanks for that.
