What our development finance service does

The work we do on a development, from feasibility to exit

Development finance funds the construction of multiple dwellings for sale or for holding, and it is assessed on the project rather than mainly on you. Lenders look at the feasibility, the land value, the total cost to complete and the realistic end value, then size a facility against those numbers.

Developers come to us when a bank has said no on a project that is fundamentally sound. Often the issue is presales, or the structure, or which lender it went to.

Every facility is subject to lender approval and your circumstances, and the terms are short — they run to the end of the project rather than for thirty years.

  • We test the feasibility before approaching any lender

    We review the feasibility, the site and your experience first. If the numbers do not work you hear it from us, rather than after three declines have already been recorded against the project.

  • We size the facility against cost and end value

    Total development cost, gross realisation value, loan to cost, loan to value, presale cover and your profit margin decide almost everything. Understating total cost is the most common feasibility error, and a valuer engaged by the lender will test your end values against comparable sales anyway.

  • We put bank, non-bank and private funding side by side

    Cost of funds is only part of the picture on a development. A facility that costs more but settles two months sooner can be the cheaper option once holding costs are counted. We model both over the actual term of your project, then you pick.

  • We present the project and negotiate the terms

    We take the file to the lenders whose appetite fits it and come back with indicative terms, so you compare cost, conditions and timing side by side rather than one offer at a time.

  • We manage the valuer and the quantity surveyor

    The lender engages a quantity surveyor to review your construction costs before approval and to certify progress claims during the build. Their reports control the drawdowns, so keeping that process moving is how the site keeps moving.

  • We plan the exit before the first drawdown

    The facility is repaid from the sale of completed stock or refinanced to a hold facility, and interest is usually capitalised so the debt grows through the build. A facility that expires before your stock is sold turns a good project into a distressed one.

How Perth developments get funded

Four funding sources, and the trade-off in each

There is no single best source. The right one depends on the size of the project, your equity, your experience and how fast you need to move. Non-bank and private lenders will often fund without presales at a higher cost, and on a small project with a strong site that can be worth it.

Major bank

Tends to suit

Experienced developers with presales and strong equity

Trade-off

The cheapest money, and the slowest and most conditional

Second-tier and non-bank

Tends to suit

Sound projects that miss one bank criterion

Trade-off

Costs more, with more flexibility on presales and structure

Private lender

Tends to suit

Short timeframes, unusual sites, or no presales

Trade-off

The most expensive, and the fastest to move

Mezzanine or second mortgage

Tends to suit

Filling an equity gap on an otherwise fundable project

Trade-off

Expensive, and it needs the senior lender's consent

Knowing the funding sources does not hurt. Do not stress about which one your project needs — bring us the feasibility and we tell you who will look at it and on what terms.

Who development finance suits

The projects we arrange funding for

Small to mid residential and mixed-use, from a two lot subdivision through to a mid-sized apartment build. These are the situations that arrive most often.

  • Developers building two to twenty dwellings in the Perth metro area

  • Owners subdividing a battleaxe or corner block and building out

  • Builders developing their own stock alongside contract work

  • Investors moving up from a single build to a multi-dwelling project

  • Anyone with a site, a feasibility and a bank that has gone quiet

How a development facility runs

Five steps, with a valuer and a quantity surveyor added

The steps are the same as any file we write. The difference is how much work happens before the application is submitted, because a development is won or lost on how the feasibility is presented.

  1. Start an application

    You send us the basics and we work out what you could borrow and which lenders will look favourably at your situation.

    What you need

    Income, debts, deposit

  2. Get pre-approved

    We put your file to the lender that fits and bring back a pre-approval in writing, subject to lender approval and your circumstances.

    What we do

    Match the lender to your file

  3. Get officially approved

    Once your offer is accepted, the lender orders its valuation and issues formal approval.

    What we do

    Chase the lender, so you do not have to

  4. Prepare for settlement

    We go through the loan documents with you before you sign anything, then coordinate the lender and your settlement agent.

    What you need

About our independent mortgage brokers

The brokers who take your project to market

Independent means no franchise above us and no lender owning a share of the business. Nobody upstairs sets a monthly target, so a project goes to the funder whose appetite fits it rather than the one on a scoreboard. Your bank has one credit policy; we compare 40+ lenders.

Gavin Harrigan has been broking from West Leederville since 2005. Today it runs on a small team, Gavin Harrigan, Justin Richardson and Xavier Prescott, each with their qualifications on the page. You deal with the person who writes your loan, before settlement and after it.

The work runs from a first home loan, through refinancing and investment lending, out to construction, small developments and commercial property. Same broker, whichever end of that you are at.

Why choose us for development finance

A declined project is usually a mismatched lender, not a bad site

Every point below is a consequence of how this business is owned, not a slogan about service.

  • Included

    No franchise, no head office quota

    We do not pay a franchise fee, so nobody upstairs sets a monthly target for us to hit. That removes the main reason a broker recommends the wrong loan.

  • Included

    No lender owns a share of us

    The banks have no stake in this business and no claim on where files go. Your bank has one loan to sell you. We do not.

  • Included

    40+ lenders, one shortlist

    We compare 40+ bank and non-bank lenders, then explain why the shortlist looks the way it does. Policy differences decide more applications than rate does.

  • Included

    We will tell you when the answer is no

    If refinancing does not actually save you money, we say so and you leave the loan where it is. A wrong loan costs more than the fee it earns.

  • Included

    The same broker after settlement

    You keep dealing with the person who wrote the loan. We review it as rates and your circumstances change, not once and then never again.

Common questions about development finance in Perth

How much equity do I need for a development?

It depends on the lender, the project size and your track record. Facilities are sized against total cost and end value rather than by a single rule. Bank funding generally requires more equity than private funding. We work out the realistic requirement for your specific project before approaching anyone.

Do I need presales to get development finance?

Banks usually want presale cover, though the level varies by lender and project. Non-bank and private lenders will often fund without presales at a higher cost. For smaller projects, the cost of moving faster is sometimes less than the cost of waiting for contracts.

How is development finance different from a construction loan?

A construction loan funds one dwelling and is assessed largely on your income. Development finance funds multiple dwellings built for sale and is assessed on the project feasibility, cost, end value and exit. Interest is usually capitalised into the facility rather than paid monthly.

What is a quantity surveyor's role in the funding?

The lender engages a quantity surveyor to review your construction costs before approval and to certify progress claims during the build. They confirm the work claimed has actually been done and that the remaining budget still covers the remaining work. Their reports control the drawdowns.

Can a first-time developer get finance?

Yes, though the terms reflect the lack of track record and lenders look harder at the builder and the site. A modest, conservative first project presented honestly funds far more easily than an ambitious one. Pairing with an experienced builder strengthens the application considerably.

What happens if the project runs over budget?

You fund the overrun, usually from your contingency or your own equity, because the facility is sized at approval. Some lenders will consider an increase, though it involves a fresh assessment and takes time. This is why a genuine contingency belongs in every feasibility.

Can I keep one of the dwellings instead of selling?

Yes, and it needs planning from the start. Retaining stock means refinancing that dwelling to a hold facility at the end, which requires serviceability rather than sale proceeds. Tell us at the outset so the facility and the exit are structured for it.

What size projects do you arrange finance for?

Small to mid residential and mixed-use, typically from a two lot subdivision through to a mid-sized apartment build in the Perth metro area. If a project sits outside what our panel will fund, we will say so early rather than shopping it around without result.

How do lenders size a development facility?

Off four numbers. Total development cost covers land, construction, professional fees, interest and contingency, and understating it is the most common feasibility error. Gross realisation value is what the finished stock should sell for net of selling costs, and an independent valuer checks it. Loan to cost sets how much equity you put in, and loan to value measures the debt against the end value.

What goes in a feasibility that gets funded?

Site details with zoning, the R-code and the yield; land cost including duty; construction cost from a fixed price contract or a quantity surveyor; professional fees for architect, engineer, surveyor, planning and legal; council contributions and headworks; finance costs including capitalised interest; selling and marketing costs; a contingency you would be comfortable defending; end values supported by comparable sales; and a programme from settlement to final sale.

How is a small infill subdivision funded?

It sits awkwardly between a construction loan and a full development facility, and some lenders will treat a two dwelling build as residential construction, which is cheaper and simpler if you qualify. What decides it is zoning and the R-code, whether the titles will be green title, survey strata or built strata, the subdivision approval conditions, and the service connections, drainage and retaining required.

What should I check about presale requirements?

Which lenders require presale cover and which will consider a project without it, whether related-party sales count towards the requirement, how deposits are held and whether they count as equity, the sunset clauses and how long your contracts stay binding, and the cost of a non-presale facility against the cost of waiting for contracts.
