Hardwood floors throughout..

My sub floors are hardwood soI'm hesitant to paint them.

The property I'm putting an offer on has hardwood and vinyl/linoleum on the bottom floor.

I do more engineered hardwood than anything else. 

But flooring could be up to 3 different people, if you are doing a combination of carpet, tile and hardwoods.  

We have Newly refinished hardwood floors (About 1500 sqft worth) /our Lower Level is Carpet and tile.

They had access to more materials such as real, thick hardwood floors. - More attention to detail and craftsmanship.Cons:- May not be up to the latest city codes.

@Lindsay Conway I uses vinyl peel and stick flooring that looks like hard wood.  

To give a little information it’s a duplex, each side is one bed-one bath, completely remodeled in 2016 with new kitchens bathrooms, oak hardwoods.

I'd rather not lose the 1k in materials I spend on the upstairs plus the probably 1k in labor to install, but I really don't see it being correct to have two different types of hard wood floors in the house.
