Can They Apply For Spouse Visa?

My cousin is British.
His wife and 2 kids are in India.
He is currently not working and lives mostly in India.
He has sold his house in the UK and put one hundred thousand pounds in his bank account from the sell
He is waiting for 6 months to pass
After 6 months will he be able to apply for spouse visa for his family?
He will show the money in the bank
During the 6 month wait he will be living in India
Is this accepted?

When his family come to the UK they will rent a house out

Are the children British also? Either way the savings are more than enough to meet the requirements.
With regards to cash savings from property - if the house was sold in the last 6 months they can apply straightaway as long as they have proof that they owned the property before.

…cash savings held at the date of application are the proceeds of an applicable property sale; the period the property was owned in the 6 months prior to the date of application, before it was sold to produce cash savings, can be counted towards the 6 month period. So money held as cash savings at the date of application can have resulted from the sale of a property for the first part of the period of 6 months prior to the date of application and as cash savings for the rest of that 6 month period if the decision-maker is satisfied that all the requirements in paragraph 7.4.10. have been met in addition to the requirements being met when the funds are held as cash savings (see the table in 7.4.3. for a summary of the cash savings requirements). The rules do not specify what evidence must be submitted as individual circumstances and local property laws and taxes will vary. However, to assist applicants and decision-makers, the rules give examples of some evidence we will take into account. But other evidence may be accepted if it indicates the requirements are met.
