Of course the advice wouldn’t be the same! The concept of LFO’s is a relatively recent one and so there will be a cut off date before which no such thing would have existed and so it’s pointless looking for one!
You think you’re gonna get an LFO on a house built in the 50’s, 60’s or 70’s? You could all, with the best of intentions, be leading poor Wendy on a wild goose chase. Not everyone is buying new, off-plan or nearly new properties!
