Moving into one partner's home: what is the other one really paying for?

Put in the mortgage payment and how long you've been doing this. We'll tell you what part is living there and what part is the home itself. Here, Blue is the one moving in and Orange is the one who owns the home.

// a home that isn't Blue's$15,000over 5 years, what Blue puts into Orange's home

If you haven't put it in writing, it's as if Blue had gifted $15,000 to Orange. Nobody means any harm: almost nobody thinks about it when moving in.

a month. The home and the mortgage are only Orange's.

// three arrangements
// arrangement 1

Pays only the living part, like rent

Pays per month
$200
Gifted after 5 years
$0

Orange pays the rest ($700 a month) and the home stays only Orange's. It's the cleanest option: each of you knows what you're paying.

// arrangement 2

Pays half, with that share in writing

Pays per month
$450
Principal on record after 5 years
$15,000

A document signed by both of you stating what each contributes every month. That way the $15,000 of principal doesn't get lost: it's on record as what Blue put in. If you want it to hold up, a lawyer can make it airtight.

// arrangement 3

Pays the living part and saves the rest in their own name

Pays toward the home
$200
Saves in their own name
$250
Saved after 5 years
$15,000

It costs the same out of Blue's pocket ($450 a month), but $250 goes into an account of their own instead of into Orange's home.

The problem was never paying half. It was not knowing what you were paying for.
