Reminder: Pay 1.9% credit card fee on your rental payments with RentHero

Don't pay through the nose when you use a credit card to settle your monthly rent in Singapore. Check out our deal with RentHero, soon including a KrisFlyer UOB credit card option.

EXPIRED This article relates to an offer or promotion which has now expired.

Cover Day

Note: RentHero now has a 1.75% fee offer for all users, replacing our previous reader offers.

We wanted to do a quick reminder post today about our special offer code with RentHero, which gets you 15% off their usual fee for paying your rent in Singapore with a number of popular miles earning credit cards.

Several of our readers have already signed up with the payment service since our offer launched in February, and this is a great way to boost your annual miles earning at a competitive ‘cost per mile’.

Our offer

New RentHero customers making rental payments between now and February 2020 who apply promotion code MAINLYMILES will enjoy a discounted fee of 1.90%. This applies to both one-time and recurring payments.

That’s a 15% saving on the usual fee RentHero charges, already a competitive rate in the market at 2.25%.

Supported cards

RentHero currently supports seven major miles earning credit cards in Singapore. We spoke to the team this week and they confirmed that the new KrisFlyer UOB credit card, which we comprehensively reviewed last week, will also be eligible for their service in due course.

Card 2

We have therefore updated the earning and cost per mile tables below to include this payment option.

The top two here for value are the UOB Reserve Visa, at 1.17 cents per mile, and the more accessible BOC Elite Miles card at 1.24 cents per mile.

Even at the upper end, 1.55 cents per mile with cards like the DBS Altitude Visa (and the new KrisFlyer UOB card) are justifiable miles purchase rates for most (we aim to get 2+ cents per mile on redemptions and actually achieve closer to 3 cents per KrisFlyer mile, even by some pessimistic valuation assumptions).

You’ll notice a couple of popular credit cards are missing from RentHero’s list, that’s due to the nature of RentHero being a rental payments only facility, with that payment category except from miles earning in the terms and conditions of certain cards like the Citi PremierMiles Visa and OCBC Voyage.


Miles earned example

Here’s how RentHero illustrates the number of miles you can earn in a year, with an example for a rental payment of S$5,000 per month using the BOC Elite Miles World Mastercard as the payment method (earning 1.5 miles per S$1 spent).

5k example 1.jpg

In this example you’re ‘buying’ miles at 1.47 cents each (S$1,350 / 92,025). That’s based on the standard 2.25% fee charged by RentHero.

Let’s take a look at the same rental over a year, paid using the MAINLYMILES promo code with a 1.90% fee.

5k example 3.jpg

First thing you’ll notice is that you’ll actually earn fewer miles using our promo code. That’s because the fee is lower, and since the fee is also charged to your credit card it is also eligible for miles earning.

The key here is the rate at which you’re buying the miles. With this lower 1.90% fee, assuming you are using the BOC Elite Miles card, the miles ‘purchase’ rate is 1.24 cents each (S$1,140 / 91,710), over 15% cheaper than at the normal rate.

RentHero won’t always be the cheapest way to buy miles when making your monthly rental payment, even using our 1.9% promo code, so remember to shop around.

For Citi credit card holders in Singapore, Citi PayAll now offers a 2.0% fee (1.5% for some users). Given that Citi cards are not eligible RentHero payment methods, PayAll may be your cheapest option.

If you’ve been selected for the 1.5% PayAll fee, with the exception of the Citi PremierMiles Visa, it is basically the cheapest method around for rental payments.

The following table assumes the 1.9% promo code (Mainly Miles reader rate) for RentHero, compared with the regular rates for CardUp, ipaymy and Citi PayAll.

Again we’ve added the upcoming KrisFlyer UOB credit card for comparison.

Table assumes CardUp fee for rental payments of 2.6%, ipaymy of 2.25% (3.3% for Amex), Citi PayAll based on the rate applicable to your account (1.5% or 2.0%). Promotion codes are sometimes offered for other payment facilities and are not reflected here.

As you can see with the exception of Citi PayAll, our promotional rate with RentHero is the cheapest way to pay rent in Singapore with most of the popular cards listed above.

For example if you hold the BOC EM card and the Citi PM Visa card, even if Citi are quoting you the 1.5% PayAll rate, RentHero with BOC EM comes out better.

  1. Hi Andrew.. Would you know..? especially in light of current presumably-true troubles that Mileslife is going through.. Would RentHero be paying the rent before they charge our credit card or after? What or who stops RentHero from charging to our credit cards and then not paying our landlord(s)?

    1. I believe the rental is paid to your landlord after the funds are received by RentHero from your card. Otherwise if your card is declined, then it turns out you can’t pay, they are going to be significantly out of pocket.

      Obviously I cannot personally guarantee 100% safety and security of any company, however from the FAQs section of their site:

      How secure is RentHero?
      RentHero does not manage or store your full credit card number. We use a PCI approved payment gateway certified to PCI Service Provider Level 1, the highest level of certification available in the payments industry.

      Are my payments safe with RentHero?
      All payments are made and held in a secure local bank in Singapore and are separate from our operational funds. Monies received never spend more than 48 hours in our bank account as we tend to receive payments on or 1 day in advance of the due date.

      Hope this helps!

      1. Thanks for the quick reply, Andrew.. Yeah.. I’ll pass on this one.. especially after getting a bit burnt (overall, not too badly, but still..) from Mileslife..

        Using banks as the instrument, no problem.. but using an unknown, with no real assurance.. for small amounts, fine.. not for $10,000 a month, I think..

        Still.. thanks for all the great work both you and Eddie do here… 🙇🏻🙇🏻
