David,
Found this picture with the picture of Cherry Ole so called. Could be my aunt's scrawl and the name may be wrong. Agree the house looks as if it is not quite finished.
This car in driveway may belong to Charles and Ethel or it may belong to owners of house. Man on running board is unknown to me and I don't recall a picture of Charles and Ethel with a car with whitewall tyres.
It does not look cheap so assume the house was unfinished and not falling down if it belonged to owners.
