NSW Development Site Specialists

Keep the house.
Add two more.

For first- and second-time developers in NSW — builders, investors, and trade operators ready to run their own project, not a course about one.

We find sites where you can retain the existing dwelling and add one or two more on the same lot. CDC pathway preferred. Illawarra, Sydney, South Coast, Sutherland Shire, Newcastle.

Who We Work With

Four types of client.

We don't work with everyone. Mosros is built for the people most buyer's agencies ignore — first-timers, trades, and small operators who want to do the work properly. If you see yourself below, we can probably help.

01 / Builders

The trade-builder who's ready to develop their first one.

You build for other people. You know what a good site looks like. What you don't have is a sourcing pipeline or feasibility muscle. We are that pipeline.

02 / First Developers

Stepping into property development for the first time.

You've seen the upside, you have the capital position, but you've never run one yourself. You want a sourcing engine and an honest feasibility before any contract — not a course about how it might work.

03 / Investors

Equity-rich investors graduating from yield to development.

Equity-rich and ready to step up from yield-focused rentals to manufactured equity. You want feasibility modelling on every site before you make an offer, not after.

04 / Scale-ups

Developers between project two and five, refining the machine.

The build isn't your issue. Site selection is. We do the feasibility modelling before any offer so you stop losing margin on the land.

The Approach

KEEP + ADD.

Demolition-rebuild is a 1990s playbook. On CDC-friendly 600sqm+ R2 lots, retaining the existing dwelling and adding one or two more is almost always the higher-yield play. Faster approval. Lower build cost. Rental cashflow from settlement.

Most Buyers' Agents

Hunt the knockdown.

The mainstream playbook is to find a block with an end-of-life dwelling, demolish, and build two or three new homes. It looks simple on paper.

In practice: you lose the existing rent during build, carrying costs compound, and if council stalls the DA you're holding land that isn't generating anything.

Mosros

Hunt the retain.

We specifically source 600sqm+ lots in R1, R2 and R3 zones where the existing house has rental life, and one or two dwellings can be added behind or beside under CDC or a clean DA pathway.

Front house keeps paying rent while you build. Margin compounds. Finance stays cleaner. The feasibility stacks before you commit to contract.

How It Works

Three steps.

We keep the process tight. One call to understand fit. One engagement to do the work. One settlement to complete the job.

i.

45-minute Site Briefing

A 45-minute Zoom. We walk you through our acquisition process, evaluate the opportunities matching your area of interest, and review live NSW development sites alongside recent case studies. You leave with clarity, not a pitch.

ii.

Twelve-Month Engagement

If we're a fit, we take you on exclusively for twelve months. Weekly progress updates. Direct vendor outreach. Full CDC and DA pathway assessment on every candidate site. A retainer that protects your time as much as ours.

iii.

Advisory Through Settlement

Once we've identified the right site, we coordinate with your solicitor through exchange and settlement, with feasibility and pathway advisory maintained through DA or CDC lodgement. Then we hand the keys to your builder.

The Fee Structure

No hidden fees. Here's the deal.

Engagement Retainer
$10,000 + GST

Non-refundable, but 100% credited to the success fee on a completed acquisition. Covers feasibility work, GIS mapping, and vendor outreach regardless of whether you transact.

Success Fee
3% at settlement

3% of purchase price, payable at settlement, with the engagement retainer credited. No vendor commissions, ever.

About Us

Property as a technical challenge, not a commodity.

Mosros Property Consulting is a NSW-focused development consultancy operating across Illawarra, Sydney, South Coast, Sutherland Shire, Newcastle and the Hunter.

The firm works to a single discipline: capital protection comes before upside on every brief. No site is presented to a client unless the modelled margin clears the buffer required for the things that can't be modelled — interest rate moves, build cost drift, market softening between approval and sale. Conservative feasibility, every time. The numbers go in before the offer goes out.

The methodology underneath that is deliberately technical: GIS-led site identification, conservative feasibility modelling, and relationship-based vendor negotiation. Mosros doesn't bid against the market. It finds the lots most agents and clients miss, then structures acquisitions where the vendor circumstances and the buyer's terms actually align.

The way Mosros frames its role — a safety net for developers. The big consultants work for the big end of town. The agents on television sell interstate rentals for yield. Nobody is looking after the builder who's been renting plant for someone else's project for twenty years and finally wants to run his own site, or the investor with equity ready to deploy and no one honest enough to model the deal properly before the contract.

That's the job. Ethical asset management: treat each site as a technical problem with a specific answer, not a commodity to be marketed. Find the answer before the client signs.

Common Questions

Before you ask.

The things most clients want to know before the first Zoom. If your question isn't here, it's one we can cover on the call.

Do I need to have developed before?+
No. A significant portion of our clients are first-time developers — builders doing their own first project, or equity-rich investors making the leap from rentals. The engagement includes end-to-end guidance through feasibility, CDC/DA pathway, vendor outreach, and solicitor coordination to settlement.
What regions do you cover?+
NSW only. Within NSW, our active sourcing spans Greater Sydney, the Illawarra (Wollongong through to Kiama), South Coast down to Nowra, and the Newcastle and Hunter region. We do not take on clients targeting QLD, VIC, or other states — different planning regimes, different expertise required.
What happens if no site suits me within twelve months?+
The engagement retainer is non-refundable — the feasibility, GIS mapping, and vendor outreach work happens whether or not you transact. This is disclosed up front. We can extend the engagement by written agreement if the market has been difficult in your region. What we don't do is push you into a site that doesn't stack just to close out the engagement.
Do you take commission from vendors or builders?+
No. Our only revenue is the engagement retainer and the success fee, both paid by the client. We have no referral relationships with vendors, selling agents, or building companies that would compromise our judgment on whether a site stacks for you.
Why only 8 clients per quarter?+
Because proper feasibility modelling, direct vendor outreach, and weekly client updates take time. Eight per quarter is what we can deliver to standard. Beyond that, quality drops — and the whole proposition rests on quality.
