What to do seller has dementia

[Royce Talbo]

I came across this elderly man through my work and he mentioned about selling his place and asked if i knew a realtor. He wants$770k arv is $1.1m from what he described needs about 100k in repairs. Going to look at the place next week.

The thing is he mentioned he has dementia. Wife passed no children living in state. How do i approach this without looking like i am taking advantage of the elderly. Again he brought up the subject of selling not me.
