You need to be more creative with the answers to the questions in the visa application without telling lies. You need to submit ALL documents of any property she owns .. these must be translated, names DOB of her parents and any children. You should hand write a letter stating that you will be paying in full for the trip including air fares and spending money and sign it . State that you will travel to and from the UK on the same flights with ESTIMATED DATES. Add in a copy of your passport.
