The design on the first card back above is typical of a late 1860s cdv, so is presumably from the first year or so at this address. The second one above is perhaps a re-photograph of an earlier print - the lady is certainly a bit behind the times for the early 1870s. The sequence of these two is not certain.
The first cdv below is on a rather poor quality card with a design on the back which would suggest a date towards the end of this period. The ladies' costumes on the one below it, which has the same reverse design, are also typical of the mid 1870s.
