Private tenants rights re viewings!!!!?

To cut a long story short, I am a private tenant who agreed with landlady that we could rent the house with view to buy - our contract states that - ' it has been agreed that between both parties that the property will be let until a time when the current occupiers (us) are in a position to purchase the property at full market value.'
We are not in a position to buy as I have just started maternity leave - due in Dec - she has been pestering us for months about when did we want to buy etc - in which we explained the pregnancy - mat leave etc - and nothing was said, other han she has kept in increasing the rent (? try and force us out).
Anyway we had a txt saying she was putting rent up again last night and that she wnted to sell soon, my cousin (her friend) rang her and it turns out the let to buy mortgage she has on this runs out next november, then she will have to pay capital gains which she does not want to do, therefore she wants to sell before. Is she breaching the contract as

she knows we are not in a situation to buy at market value? She has told my cousin she will want to put the house up fpr sale in march to ensure it sells in time - and that they would give us 3 months notice (which is what is agreed in contract if either of us wants to finish it) so in that time do I have to let people in to view - afterall I am going to have a newborn baby + breastfeeding and my partner works shifts hence no privacy!! I want to know where I stand before she decides to tell me all this herelf, as she has not yet. Thanks.

Yes,she is,see a solicitor because she is not allowed to keep putting your rent up either,there are laws in place for tenants regarding rent increases,plus you have a contract with your conditions,she hasn't got a leg to stand on.

The clause allowing you purchase rights are a bit vague. What if you are never in that position? Its not her duty to provide you with a house. Any decent lawyer could tear it apart. It might be as well to move out. To be fair to her she has herself to think about, not your family. I expect the rises in rent is more to do with the rises in interest rates that have been high.

You might as well do the decent thing and move out in my opinion.

What consideration has been exchanged here? Else, see The Office of the Deputy PM, long and short hold tenancies.

Neither you nor your landlady should have signed a contract with no time limit on it. Once she realised you were pregnant, it dawned on her that she was lumbered with you for a very long time - no wonder she panicked and put the rent up. Was this contract drawn up by a solicitor ? Yours or hers ? Either way, go and see the solicitor and get a clarification of where each party stands.

If the contract was agreed between you, without each of you having your own solicitor check it - ouch!

Sounds to me like you need to start looking for a new place to live.
Your landlord has the right to ask you to move out with 3 months notice.
She has given you first refusal on buying the property and you say you are in no position to buy.
She needs to sell the house to avoid paying lots of extra tax, fair enough, do you like paying more tax than you have too?

If this is not her primary home she will have to pay capital gains no matter what!
