When the Build Costs More Than the Bank Thinks: Valuation Shortfalls and Cost Overruns
Key Takeaways After several years of sharp increases in construction costs, a strange situation has become common across Sydney and much of Australia. It can genuinely cost more to build a home than the finished property is worth on paper. Materials, labour and builder margins have moved quickly, while valuations, which lean on comparable sales of finished homes, have not always kept pace. The result is a conversation many borrowers never see coming, where the bank’s valuer puts the completed project below what land and contract will cost. That does not automatically mean the deal is dead. It means the lender will size the loan against a smaller number than you expected, and you need a plan to close the gap. The same discipline applies once construction starts, because variations and allowance blowouts can open a second gap mid-build, when options are far more limited. Working with a construction loan broker who handles these deals daily means the risks get stress-tested before you sign, not discovered after. Why the On-Completion Valuation Can Land Below Your Costs Before approving a construction loan, the lender orders an on-completion valuation, an estimate of what the finished home will be worth once built. This anchors the whole facility, because lenders calculate your Loan to Value Ratio (LVR) against the lower of total project cost and that valuation. If the valuation comes in under land plus contract, the lower figure wins and your maximum loan shrinks with it. The logic is straightforward from the lender’s side. If the project failed and the bank had to sell, it could only recover what the market would pay for the finished house, not what you spent building it. Valuers justify their figure with comparable sales of completed homes, and when build costs rise faster than local sale prices, the comparables do not support a valuation equal to your outlay. Nobody has erred. Cost and value have drifted apart. Certain projects are more exposed, including highly customised homes, builds in areas with few recent comparable sales, knock-down rebuilds on expensive land, and premium inclusions that add modest resale value. Worked Shortfall Scenario Illustrative figures make the mechanics easier to see. Say you buy land for $600,000 and sign a fixed-price building contract for $550,000, a total project cost of $1,150,000. At around 80% LVR, you expect a loan of about $920,000, contributing roughly $230,000 yourself. The valuer then assesses the on-completion value at $1,050,000, which is $100,000 below your total cost. The lender now lends against $1,050,000, not $1,150,000. At around 80% LVR, the maximum loan becomes about $840,000, down from $920,000. The project still costs $1,150,000, so your required contribution jumps from about $230,000 to about $310,000. A $100,000 valuation shortfall has become roughly $80,000 of extra cash to find, on top of everything already budgeted. The shortfall does not reduce the loan dollar for dollar. It shrinks the valuation base the LVR is applied to, so even a modest-sounding valuation gap can produce a significant cash gap. Your Options When the Valuation Lands Short A short valuation is rarely a single forced move. There are four levers, and many borrowers pull more than one, depending on the size of the gap, the cash or equity available, and the builder’s flexibility: Contributing a Bigger Deposit The simplest response is to close the gap with your own funds, whether savings, a family gift, or usable equity in another property, keeping the project intact and on schedule. The honest question is whether more cash still leaves enough buffer for the build itself, because a reserve emptied at approval leaves nothing for overruns later. Re-Scoping the Fixed-Price Contract Working with the builder to remove or defer items that cost a lot but add little valuation can narrow the gap directly. Premium appliances, landscaping, pools and high-end finishes are common candidates, and some can be completed later with savings. Re-scoping works best before the contract is signed, since afterwards changes become formal variations with their own costs and delays. Testing Another Lender’s Valuers Valuation is an opinion built on evidence, and different lenders use different valuer panels who may select different comparable sales. Two valuations on the same project can differ by tens of thousands of dollars, particularly in suburbs with thin sales data. A broker with a wide panel can order upfront valuations through several lenders before you commit anywhere, which is one reason borrowers use a Sydney mortgage broker for construction finance instead of accepting whatever number one bank returns. Pausing to Reassess Sometimes the honest answer is to wait. Where the gap is large, reserves are thin and the contract cannot be trimmed, pushing ahead leaves you exposed to any mid-build problem. Pausing to save more, letting local sales evidence catch up, or re-tendering the build are legitimate outcomes, and a project delayed on your terms is usually far cheaper than one that stalls halfway. Mid-Build Cost Overruns, the Second Danger Zone Even a project that starts with the numbers aligned can drift once construction is underway. Overruns typically arrive through three doors. Variations are changes made to the contract after signing, each adding cost outside the approved amount. Prime cost items are allowances for products not yet selected, such as tapware or appliances. Provisional sums are allowances for work not yet fully priced, like excavation or rock removal. When real prices exceed the allowances, and in recent years they often have, the difference is yours to fund. The part that surprises people is that the lender generally will not just top up the loan mid-build. A construction facility is approved against a specific contract, valuation and set of circumstances. Asking for more money halfway through is effectively a new application secured against a partly built house, which is difficult security to value and to sell. Income would be reassessed and valuations reordered while progress payments may sit on hold, with no guarantee of a yes. That is why lenders typically require variations to be paid from your
Releasing Equity Above 80% LVR: When Paying LMI Is Worth It
Key Takeaways Read almost anything about equity release and you meet the same line. Lenders let you cash out to 80% of your property’s value, and that is the end of it. Many borrowers treat an 80% loan to value ratio (LVR) as a legal limit. It is not. It is simply where most lenders stop lending without lenders mortgage insurance (LMI). Beyond it, a smaller group will still consider cash-out to around 85% to 90% LVR, provided you pay the premium and can show clearly what the money is for. That is a real decision for investors with some equity but not quite enough. An equity loan broker can model whether paying a four- or five-figure premium to release the funds now beats waiting for repayments and price growth to lift your usable equity past the 80% line. The honest answer depends on the numbers, and they cut both ways. Why Lenders Restrict Cash-Out Above 80% LVR The 80% threshold is not arbitrary. Above it, the buffer between the loan balance and the property’s value narrows, so a modest price fall could leave the loan worth more than the security behind it. LMI transfers that risk, protecting the lender, not you, if the loan defaults and the sale does not cover the debt. Because claims are likelier at higher LVRs, both the lender and the mortgage insurer scrutinise these applications closely. Cash-out adds a second layer of caution. When you borrow to buy, the lender sees exactly where the money goes. When you release equity as cash, they cannot, so credit teams worry about funds drifting into gambling, business losses or living costs. High-LVR cash-out therefore carries tighter conditions than a purchase at the same LVR: In practice, your current lender may refuse cash-out above 80% while another considers it routinely. Policies vary widely, which is where a broker comparing a wide lender panel earns its keep, matching your purpose and profile to a lender whose credit policy allows it. What Purpose Evidence Lenders Ask For The biggest difference between cash-out at 75% and at 88% is the evidence standard. Below 80%, many lenders accept a declared purpose with light documentation. Above 80%, expect to substantiate it: Where the purpose is a future purchase, some lenders release equity above 80% as a defined deposit fund, which pairs naturally with pre-approval for an investment property loan on the new purchase. Arranging both pieces together usually produces a cleaner outcome than handling them separately. Paying LMI Now Versus Waiting The decision comes down to numbers, all illustrative only, since premiums, growth rates and valuations vary. Suppose your home is valued at $1,000,000 and you owe $750,000, a 75% LVR. Cash-out to 80% releases $50,000, not enough for a deposit plus stamp duty and costs on the $750,000 investment property you want, before you even test your borrowing capacity on the new loan. Cash-out to 88% releases around $130,000, which is enough, but at 88% LVR the LMI premium might be around $12,000, typically capitalised onto the loan: When Paying LMI Wins Say the market you are buying into grows around 5% a year. On a $750,000 property, that is roughly $38,000 in year one and around $77,000 over two years. If waiting two years is what it would take to build the extra equity without LMI, the comparison is a one-off cost of about $12,000, plus perhaps $1,500 of interest on the capitalised premium, against roughly $77,000 of extra entry price and a larger deposit needed later. In a genuinely rising market, the premium can look cheap. When Waiting Wins Now run the same scenario with flat prices. Two years of principal repayments, say $30,000, plus modest growth on your own home could carry your usable equity above the line without LMI at all. The $12,000 premium, the interest on it, and any rate loading that sometimes applies above 80% LVR are then pure cost. If prices fall, waiting wins twice, because you avoid the premium and buy cheaper later. Waiting also keeps repayments lower, which matters if your income is variable or your buffer is thin. When a Smaller Release Wins There is a middle path between paying full LMI at 90% and waiting. Cash-out to 83% or 85% attracts a much smaller premium than 90%, and pairing a smaller release with a cheaper target property sometimes closes the gap on its own. Where the extra funds you need are modest, a partial step above 80% can cost far less than the leap to the top of the range. Capitalising LMI Most borrowers do not pay the premium in cash. Lenders usually allow it to be capitalised, added to the loan balance, so a $130,000 cash-out with a $12,000 premium becomes a $142,000 increase to your debt. Three things are worth understanding first: One point investors often miss is the tax treatment. Where the released funds are used for income-producing purposes, LMI may be treated as a borrowing cost deductible over five years or the life of the loan, whichever is shorter. How the treatment applies depends on how the funds are actually used, so raise it with your accountant rather than assuming it applies. Weighing the Decision Before You Commit There is no universal answer, but there is a sensible order to the questions before paying LMI on a cash-out: Where most of these point the same way, the decision usually makes itself. Where they conflict, modelling the scenario across several lender policies is worth an hour of your time. When the Premium Buys You Time The 80% ceiling is a default, not a wall. For an investor short of a deposit in a rising market, paying LMI to release equity above 80% can be a calculated cost that buys entry years earlier. In a flat or falling market, the same premium can be money spent for nothing. What settles it is honest numbers on both sides, run against the policies of lenders that actually allow the release.
