Rentvest your way into a better home!


Following on from my previous post about rentvesting for the first home buyer, I am going to explore the strategy of how home upgraders could Rentvest their way into a better home.

Just as the Sydney and Melbourne property markets have locked out many first time buyers, they have also restricted many second and third time buyers from upgrading. Even if these existing home owners sell and then buy in the same market the moving costs and additional loan commitments can be significant.

Once you take into account selling costs of around 3% and then buying costs of about 5%, along with removalists, utility costs, storage, cleaning etc you could be looking at taking a big hit to your equity.

If you go down the upgrading path you are locking yourself into more non-deductible (bad) debt and restricting your capacity to invest into income producing assets. Remember that the journey towards financial freedom involves reducing non-deductible debt whilst building an investment portfolio that pays you a passive income, using deductible (good) debt.

As an upgrader, you could Rentvest as a more effective strategy to maximise your investment potential and achieve financial independence much sooner. This strategy would involve turning your existing home into an investment property and then renting a more suitable property yourself.

Let’s have a look at an example to demonstrate the difference between upgrading and the Rentvest strategy:

A typical couple own a 3 bedroom house in the northern suburbs of Sydney and would like to upgrade to a bigger 4 bedroom house to accommodate them and their growing kids. Their house is currently valued at $1.2 million and they owe $600,000 on their mortgage. Their current loan repayments are $743 per week and home expenses are $123 per week, so it costs them $866 per week to live where they are.


They would need a budget of around $1.6 million to get a larger house that suits their future needs. Selling, buying and moving costs would be about $120,000. This would leave them with $480,000 as a deposit and therefore a new loan of $1.12 million. Assuming the same home expenses but with higher repayments of $1,387 per week, it would cost $1,510 per week to live in the bigger house.


Rather than sell and buy, they could rent out their existing home for $800 a week and then rent somewhere bigger themselves. Let’s look at the cash flow calculation to see how their home would perform as an investment:

Cash Flow(Positive)$4,024
Rental Income($800pw rent)$41,600
Interest($600,000 @ 5%)-$30,000
Management Fee(6%)-$1,800
Council Rates($400 pq)-$1,600
Water Rates($300 pq)-$1,200
Insurance($150 pm)-$1,800
Maintenance($150 pm)-$1,800
Actual Loss/Gain(Gain)$3,400
Total Loss/Gain(Loss)-$1,600
Tax Refund(39%)$624

As you can see, their after tax position would be $4,024 positive after the first year based on interest only repayments. Assuming that our couple continue to pay principle repayments off their loan of $8,600 per year, their existing home would cost them around $4,600 each year to hold, or $90 per week.

Note: the rental yield they could achieve is 5.5% based on $800 rent per week over their original purchase price of $750,000 (not the current valuation).

With yields around 3% on homes in Sydney right now it is significantly cheaper for someone to rent a bigger house than buy it. Our couple could rent a home that is worth $1.6 million for around $1,000 per week and keep their existing house as an investment. This equates to $420 less per week than buying the equivalent home!

What’s more, they could use that $420 per week and the $120,000 of equity they didn’t spend to invest into a portfolio of investment properties that could accelerate their wealth much faster.

Opportunity Cost

Let’s have a look at the difference in accessible equity between the two options to demonstrate the opportunity cost of buying a bigger home:

Potential Annual Return (@5%)$32,000.00$72,000.00
Home Value$1,600,000$1,200,000
Non-deductible Debt-$1,120,000$0
Deductibe Debt$0-$600,000
Accessible Equity$160,000$360,000
Potential Investment Portfolio$640,000$1,440,000

As you can see, by selling and buying a more expensive home our couple are giving up the opportunity to leverage into a much bigger investment portfolio. In addition to spending $420 extra per week, they could be missing out on investment capital growth of at least $40,000 a year!

A more expensive home could create more capital growth than their existing house but coming off the back of a boom in prices, it is unlikely that this will occur in the short term. Their additional accessible equity would be better used to diversify their portfolio into areas that are primed to grow sooner.

Thinking of upgrading? Compare the numbers on both options and make a more informed decision before you commit to that bigger mortgage. You could Rentvest yourself into a better home.

  1. Great Post! I think its getting increasingly hard to make the argument that a 30 year mortgage at current prices is a good financial move.

    The only thing is that I’ve seen a lot of people say they were reinvesting only to blow the money they were saving on holidays! Each to their own I suppose.

      Thanks Jake, this is very true! I think people who are taking on huge owner-occupier debt at historically low interest rates are going to feel the bite when rates start to rise. Also, if someone is using Rentvesting as a way to save money and avoid a big owner-occupier debt then the savings should definitely be used to invest further, rather than blowing the money on lifestyle expenses!
