I heard yesterday on the radio that you should be able to calculate the value of a house from the rental income achievable on the property. Does anyone know this formula
You could use:
R / (i - g)
R = Annual rent less expenses
g = long term expected annual increase in rent
i = return from alternative investment %
Take a 3 bedroom house that rents for 1500pm or 18000p.a.
Say maintenance costs are 5000p.a. long term
Assume that rent will grow 2% p.a. long term.
Assume you'd get 5% as a reasonable rate of return on investments.
(18000 - 5000) / (.05 - .02) = 433,333
In the above example you are simply comparing paying rent to buying a house and living in it yourself i.e. valuing based on the rental outgo you'd have otherwise paid.
An alternative valuation involving you as landlord would require you to make allowance for:
1) income tax on rent received
2) a higher required rate of return to compensate for the risks (e.g. possibility of not being able to rent the property.
In such a situation, depending on tax, the house might be worth half of the above valuation to you as an investment property
