Retirement

I have 100k in savings, 50k in a private pension and about to receive 200k in a property sale.
I also have a house that I rent out and another home that we live in ( no mortgage)
I am wanting to retire from my job at the end of the year- I am 62 and want to help my family more especially my elderly Mother and travel. My husband is retired and receives state pension but had a small parting job that he enjoys.
Can I have some suggestions on what to do with the 200k please? Also do I best sell my home that i rent- it’s worth 350k.
I am scared about not having that income come in each month from my work- usually £1300.
Will I be okay financially?
