I still think even buying her current home with a discount is a bad idea. It's still going to be quite a large mortgage, and she will be responsible for all the repairs and maintenance, along with insurances, and the likelihood of mortgage payment price hikes. She will also not get a penny towards anything if she ends up on less income/out of work, and will very likely lose the house. Her 'right to buy' discount will be naff-all help then.
In the 1980s, many people who always rented - mostly via the council, (and so did the generations before them,) took the opportunity to buy their council house under the 'right to buy' scheme... Many 1000s of them didn't realise that they would no longer have the council doing their repairs and maintenance. Some of them kept ringing the council when they had a loose handle on a cupboard door, or a leaky tap, and they said 'not our problem now.'
And when the council came around fitting new windows (on council homes,) the ones who had bought their home got passed by of course. Cue dozens of phone calls a day from people wanting to know why the council weren't doing their windows. Genuinely 100% true. Many people were shocked that the council no longer wanted anything to do with them, and wouldn't do their repairs. (and maintain the property...)
Within about 7-10 years, some of the homes - particularly on the big council estates built in the 1950s and 1960s, were looking really shoddy. Fractured soffits, broken roof tiles, cracked brickwork, corroding window frames and doors, damp popping up, and faded paintwork and all sorts..... Some people had got so used to the council doing everything that they didn't know what to do or where to turn, And there was NO-ONE to help or advise them.
I know someone who lives in a nice rural semi detached housing association bungalow (been there 14 years,) who has recently been asked 'why don't you take the chance of a right to buy?' The bungalow (big garden/garage/carport/spacious rooms,) is worth £215K on the open market and they can have it for £130K. But their rent is £420 a month, all their repairs are done, and they don't need to worry about not being able to afford the rent, as it will be paid for them when/if there comes a time when they can't afford it. They are almost 60 too, and have no intention of taking on a £130K mortgage at that age!
Also, the housing association is just about to put FREE solar panels on the roof, put a new boiler in (the current one is 13 years old,) and put new windows in (current ones are 20 years old.) She and her DH would be bonkers to leave. That work alone is worth about 11 grand!
