The above lyrics were recorded by the Primitive Quartet

There's going to be a payday when life on earth is ore
And a heavenly mansion when I reach that other shore
I'm looking for the master the ruler of heaven and earth
And I know ill get that payday when he returns to earth

There's going to be a payday I know it won't be long
With these old heartaches and sores they then will all be gone
Beautiful walls of jasper the streets are purest gold
Well don't you want this position and be on Gods payroll

I'm glad I'm on that payroll of Jesus mighty book
For all these pleasure of Satan I forsook
Well im in the race for Jesus until He calls for me
And I know ill get that payday that he has promised me

There's going to be a payday I know it won't be long
With these old heartaches and sores they then will all be gone
Beautiful walls of jasper the streets are purest gold
Well don't you want this position and be on Gods payroll

I was actually listening to it as i read this

Its called Payday not sure who recorded it first but the Marksmen Quartet did in 1989.

Found this one . I'm not sure if it is what you are looking for
Although it mentions everything else in Heaven,
it has no mention of a heavenly mansion.

THERE'LL BE A PAYDAY
by Belinda Johnson

Down here my steps grow weary,
And the road gets rough and long;
Sometimes I think I'm all alone,
Yet I'll still carry on;
For a brighter day is coming,
And it thrills my heart to know;
There'll be a payday at the end of the road.

There'll be a payday at the end of life's road,
When I stroll down the streets of pure gold;
I'll have a crown to wear beyond compare,
Put on a long white robe;
I'll find my payday at the end of the road.

Some folks are planning futures,
As they search for earthly gain;
They're busy building hopes and dreams,
But it all will be in vain;
So I'm laying up my treasure,
And I'm working my way home;
Where there's a payday at the end of the road.

There'll be a payday at the end of life's road,
When I stroll down the streets of pure gold;
I'll have a crown to wear beyond compare,
Put on a long white robe;
I'll find my payday at the end of the road.

I'll have a crown to wear beyond compare,
Put on a long white robe;
I'll find my payday at the end of the road.

Here is a recording of it
