SQL update set column = @ parameter

Question

doeas anyone knows how to update a table where column = @parameter WHERE SELECT

Basically I have a table with the following values. Table name is UserAttribute

ID|Name       |Properties|
17|Description|Student   |
17|Contact    |JohnDoe   |
18|Description|Worker    |
18|Contact    |MaryJane  |

I can update the fields with the following query:

UPDATE UserAttribute 
SET Properties = 'Charlie'
WHERE Name = 'Contact' AND ID = 17

For the results I need I would need a query something like:

UPDATE UserAttribute 
SET Properties = @parameter
WHERE Name = Contact AND ID = (SELECT HouseNo,ID FROM Table2 t1 
JOIN UserAttribute t2 ON t1.ID =t2.UserID
WHERE HouseNo = @HouseNo)

SQL doesnt allows the execution of such a query. Any suggestion on how to write the select statement in the WHERE clause?

Thank you!

EDIT 1: Maybe the question is not the clearest, but its a bit hard to formulate a question when the problem I have is also hard to understand. Therefore I will try to write some kind of pseudo-code, hoping that it will make it a bit more clear.

UPDATE table
SET Column = 'value'
WHERE Column2 = value AND column 3 =(SELECT column from other tables)

You're close, but when you introduce two tables, you have to be consistent with the alias. So at the declaration of the update statement, you'd want to start with:

UPDATE ua1 
SET properties = 'Charlie' 

Then create a from clause just as you would with a select statement, declaring your aliases:

FROM UserAttribute ua1 
    INNER JOIN UserAttribute ua2 
        ON ua2.UserID = ua1.id 
WHERE ua1.name = 'Contact';
