Capo 2, and just three chords: E5 , A5 , B5 
 

CHORUS 
E5                           A5 
I'm building a houseboat in heaven 
    B5                       E5 
to sail those deep and holy seas 
E5                           A5 
I'm building a houseboat in heaven 
          B5                       E5 
and it's welcome aboard you sweet peace 
 
VERSE 1 
The bow she is made of solid silver 
and the hall she is made of solid gold 
she ain't much long the line's a-floating 
but she's yours, babe, to have and to hold 
 
CHORUS 
 
 
I rode my old guitar to heaven 
but heaven didn't feel too much like home 
so I'm headed out on to them lonesome oceans 
in my ruby-studded houseboat to roam
