No McBride found in
https://www.lennonwylie.co.uk/PT191213.htm#PORTAFERRYhttps://www.lennonwylie.co.uk/PT191813.htm#Portaferry the Valuation continuation books at PRONI Belfast for High St seemed a great idea to find what happened to Rose’s home after 1901
https://apps.proni.gov.uk/Val12B/RelatedVolume.aspx?6238VAL/12/B/18/20D (1899 - 1908) contain on

page 83 old property number 67 renumbered as property 30 has Samuel McBride crossed out first with Mrs inserted, outer col in red 1906
then 2nd correction in blue Eliza {Landlord change in same line from John Lennon to Ellen
},outer column in blue 1907
checking next volume
VAL/12/B/18/20E (1909 - 1919) which should show what happened to McBrides property, however revisons to numbering have taken place for High Street and become more complicated with the sudden division into odd numbers then even numbers I regret after some time I had to stop , if you have the time and energy to follow onwards please do so.
looking back to 1901 census just to make sure nothing has been overlooked
the District Electoral Division is Ards Upper containing High St Portaferry, Portaferry Quay,etc

have you seen the book eg
A guide to Portaferry and district : including a map of the town.
Imprint [Portaferry] : Upper Ards Historical Society, 1980.
there appears to be/or has been a
Portaferry family history group meeting at St James centre
have you found any connection to the parish priest Rev Francis McBride 1877-1909 at St Patricks Ballygalget Catholic Church, however I think that is about 4miles NE of Portaferry
