Where to buy textures / props for archviz ?

I am sure making your own textures and props is a good thing, but for testing purposes and portfolio pieces I would rather not burn very little time I have on custom textures / props.

Can you recommend places where I could purchase texture sets (diffuse/normal/displacement/specular/gloss/etc.) or perhaps UE4-ready materials for archviz, and props (furniture, appliances, etc.) ?

Thanks

Epic’s marketplace is your best bet.
With other sites you need to make sure they have the model unwrapped properly both for texturing and lightmapping, which isn’t very common imo.

I checked both it seems more EU oriented furniture / decor, especially Evermotion (not that it’s critical for portfolio).
