IMHO usually capital appreciation is more important than monthly return. Few reason

1) capital appreciation is income tax free whereby rental need to pay income tax
2) capital appreciation usually much faster than rental return, example, terrace vs apartment, terrace will give you negative cash flow every month after deducted your installment but after 3~5 years, your property price could be double (100% return) whereby apartment after 3~5years (50% for good location), condo like kepong sentral, (0% appreciate)

3) By comparing return yield, apartment may be 8% vs terrace 2%, diff by 6%. However when come to 5yrs, the terrace property value gained more than sufficient to cover the rental yield lost

My neighbour bought a house in Subang USJ year 2008 at RM 270k and sold RM 530k last month. Don't take rental into account, only capital appreacition make her pocket earn extra RM 260k. If that time she bought Kepong Sentral, I am sure today accumulate 4 years rental also can't beat my neighbour earning. Some more income tax free for capital appreciation, if you dont declare your rental income, LHDN will come after you in 1 day, then your nightmare starts.

Of course, the method rely on rental income called 'investment', my neighbour's method called 'speculation'
