How Much of Your House Does an Investor Deserve?

"I have a friend who wants to put up the 20% down payment I need to
purchase my house. It would be an investment by him, which he would
recover when I sell the house or in 7 years, whichever comes first. Our
problem is in determining the percent of the house value at that time to
which he would be entitled. He owns 20% coming in, but how much should
he own going out?"
The investor should receive more than 20% of house value when he exits
the relationship because you get to live in the whole house, not just in
the 80% of the house that you paid for. The challenge is to calculate
that amount in a fair way, without making it too complicated.
The key is the rental value of the house -- what the house could be
rented for if you put it on the market. This is the best measure of the
value to you of being able to live in the house. From this, deduct the
costs of maintenance, which you are responsible for, to obtain the net
rent. You owe the investor 1/5 of the net rent every month.
Note that you do not deduct the mortgage payment from the rent, because
that is solely your responsibility. If you had paid cash for your 80%
share instead of borrowing it, you would owe the investor the same
amount.
It is important for you and the investor to agree on an initial rental
value, or on a procedure for determining it. This includes agreement on
whether the initial rent will hold for 7 years, or if the rent is to be
adjusted over time. If it is to be adjusted, furthermore, you must agree
on an adjustment procedure. As an illustration of one possibility, the
rental value could be adjusted every year in line with changes in the
rental component of the Consumer Price Index.
The amount due the investor each month can be handled in at least three
different ways. The simplest way is for you to pay it in cash. If you
did that, his share of ownership would remain at 20%. In all
probability, however, both of you will prefer to defer any payments
until the house is sold or the 7-year settlement point has been reached.
Assuming payment is deferred, you could treat it as a debt to him that
accumulates over time. If you adopt this approach, you both need to
agree on the interest rate that is applied to this debt. Then at
termination, he would get 20% of the property value plus the accumulated
value of the debt. With this procedure, the investment is a combination
of equity plus debt.
A second way, which the investor will prefer if he wishes a strictly
equity investment, is to use the amount due each month (or each year) to
purchase an additional share of the equity. In this case, you have to
agree on whether the value of the house used in this calculation is the
initial value or the current value.
This decision is related to the earlier decision regarding rental value.
If the rent is adjusted every year, the property value should be as
well. Much the simplest approach, however, is to use both the initial
rental value and the initial property value throughout the term of the
deal. It isn’t as accurate but it is simpler and less costly. It avoids
having to get the house appraised every year.
A potentially thorny issue that ought to be faced at the outset is how
you treat an improvement in the house that enhances its value. If you
pay the entire cost of an improvement, the investor receives an
unjustified windfall. You would expect the investor to contribute to the
cost in proportion to his ownership share.
From the investor’s point of view, however, there is a danger that an
improvement will not increase the value of the house by enough to cover
the cost. You might want to build a swimming pool, for example, but as
an investment pools are a loser. It may be OK with you because you like
to swim, but the investor will not want to subsidize an enhancement to
your lifestyle.
It follows that the investor is unlikely to agree in advance to
contribute to any improvements that you might want to make. You are
going to have to negotiate these when they arise. For the deal to work
for both parties, you should have a good relationship.

An investor who read this article suggested another approach that he
uses. Instead of receiving a portion of the total house value for his
investment, he receives a portion of the increment in value. For
example, he provides 10% of the sale price as down payment and receives
50% of the increment in value over the period covered by the agreement.
This is a much simpler approach.
