The chords for this song revealed themselves to me last week end.
Thanks to the guy who posted the lyrics.
It is recorded in F but I found that a capo at the 5th fret played
nicely (using key of C formations).
If anyone has any corrections or improvements, please repost.

THIS OLD HOUSE
Written by Neil Young

capo at 5 ... chords as shown = formation(actual)

C(F)                              Dm(Gm)
Midnight, that old clock keeps ticking,
G(C)                         C(F)
The kids are all asleep and I'm walking the floor.
C(F)                              Dm(Gm)
Darlin' I can see that you're dreaming,
G(C)                         C(F)
And I don't wanna wake you up when I close the door.

C(F)                                F(Bb)
This old house of ours is built on dreams
G(C)                         C(F)
And a businessman don't know what that means.
C(F)                                      F(Bb)
There's a garden outside she works in every day
G(C)
And tomorrow morning a man from the bank's
C(F)
Gonna come and take it all away.

Lately, I've been thinking 'bout daddy,
And how he always made things work,
When the chips were down,
And I know I've got something inside me
There's always a light there to guide me
To what can't be found.

This old house of ours is built on dreams
And a businessman don't know what that means.
There's a swing outside the kids play on every day
And tomorrow morning a man from the bank's
Gonna come and take it all away.

Dm(Gm)                         G(C)               Dm(Gm)
Take it all away, take it all away, take it all away.
G(C)             Dm(Gm)           C(F)
Take it all away, take it all away, take it all away.

Remember how we first came here together?
Standing on an empty lot, holding hands.
Later, we came back in the moonlight
And made love right where the kitchen is,
Then we made our plans.

This old house of ours is built on dreams
And a businessman don't know what that means.
There's a garden outside she works in every day
And tomorrow morning a man from the bank's
Gonna come and take it all away.

Take it all away, take it all away, take it all away.
Take it all away, take it all away, take it all away.
