How difficult will it be to buy the vacant lot next door?

So I'm in the process of buying this home in Centralia, Washington. The home I'm buying is on a small lot on a hill and parking in front of the home is very limited.

If you go slightly up the road, there's a driveway through the vacant lot to another parking area for the home.

I'm just wondering how I would go about purchasing this lot in the future if I decided to?

Would it increase the homes value?

Could I make the two properties one property?

Would I be able to add it to my mortgage? I read that somewhere…

The assessed value is $28,000 and the owner is Dmjg Enterprises Llc. Not a lot of info on that company on Google.
