P.S. Saying кое-какие will also work in place of некоторые

Я пообещал отправить вам фотографии кое-каких домов.

In fact I would personally have used кое-какие, but that's just me.

One last thing, некоторые in that sense is very close to the English word "certain"

Cheers
Yes I know which houses and now I am going to send it to him.
So I must use nekotorye or koe-kakie
