Summarise a Shared Ownership Staircasing Notice Into the Costs and Deadlines You Need to Track

The notice buries a valuation expiry date next to a legal fee estimate next to a rent adjustment nobody flagged in the covering letter. This pulls every cost and every deadline out separately, states plainly what is fixed versus still dependent on a lender or solicitor, and gives you one page to work from instead of re reading the notice.

**Summarise the notice below into the costs and deadlines that matter:**
{NOTICE_TEXT}
1. State the current share owned, the share being purchased, and the valuation the new share is based on, noting whether the valuation is final or subject to change
2. Break down every cost mentioned (valuation fee, legal fees, mortgage broker fees, any rent adjustment after staircasing) into a simple list with amounts where given
3. Identify every deadline in the notice (valuation validity period, mortgage offer expiry, any option to buy at the stated price) and what happens if each is missed
4. Flag anything in the notice that depends on a factor not yet confirmed, such as a lender's valuation or a solicitor's timeline, and state that plainly rather than estimating it

<output_format>
- A short headline: current share, target share, valuation basis
- A cost breakdown as a simple list, each item with the amount if stated
- A deadline table: deadline, consequence if missed
- A short flagged section on anything the notice leaves open or dependent on a third party
- Tone: precise and factual, this is a financial and legal document and should read like one
