Move to a slighter bigger house, with a mortgage similar to what you already have with a view to moving again in 5 or so years to a forever room.
Or
Having seen a property that ticks all the forever home boxes already and is affordable, go for the larger mortgage (and higher rates) and have things a little tight for the next 1-2 years?
really interested in what others have done or would do. (Mortgage and insurances would be about 28% of our basic income after taxes)
