The only way I can think of to solve the mismatch is something I have used
quite often in an application

Check the house number + postcode (there is only 1 number per postcode).
For those that are still left try this

1, get the address, append the address + city + postcode etc together
2, remove all #13#10
3, remove all spaces
4, remove all vowels
5, remove all double letters (like "tt" in letters)

This should allow for spelling errors

Works fairly well.
