Cory Diary : Impact of Increasing Rates on Home Loan

As all property owners, with increasing rates and weakening economy, there is some worry we may have difficulty paying our loans. We need to have a feel to assess how much an impact it can be in the future. So here's what I did using an on-line loan calculator for my calculation.

For a respectable condo size and location, S$1.125 M dollar price tag rounded up to $900 K loan amount at 80% loan to value. Applying DBS FHR18 +1.8% ( 3rd Year ), FHR18 is around 0.6% currently per DBS website. 

Loan Rate 2.4%

This works out to $5,958 monthly repayment for a 15 years loan. That's provided monthly income hits $10,723 to get a loan and assuming you do not have any other debts like credit card or car loans. Any of this debts will hit right into the calculation of your monthly income value. So beware.

Let's ease a little and pull the loan longer to 30 years. Monthly Income requirements down to $6,735 for a monthly repayment of $3,509.

Loan Rate 2.6%

Monthly Repayment: $6,043 (15 year loan), Income Required: $10,723 ( No change )

Monthly Repayment: $3,603 (30 year loan), Income Required: $6,735 ( No change )

Loan Rate 3.0%

Monthly Repayment: $6,215 (15 year loan), Income Required: $10,723 ( No change )

Monthly Repayment: $3,794 (30 year loan), Income Required: $6,735 ( No change )

Conclusion

The delta is a few hundreds buck more monthly. While is still a hit in the pocket it doesn't look as bad as I thought it would be. One of the main reason is the repayment has two components. Interest and Principal.

For a 15 year loan of the last example, when Interest go up to 3% , Interest cost is $1,215 but the Principal amount is still $5,000 which remains unchanged. Interest/Principal Ratio is 24.3%.

For a 30 year loan, Interest/Principal Ratio is 51.8% due mainly to lower principal repayment amount of $2,500. For people who overstretch themselves to buy a property using longer repayment period, few hundreds dollar increases can be a pain as they have lesser disposable income.
