NSW Development Site Specialists

Keep the house.
Add two more.

For first- and second-time developers in NSW — the builders, couples, and investors who want to do a project properly, 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, 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 partnerships 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 / Couples

Husband-and-wife teams doing their first project together.

One keen, one cautious. Both right. We run our briefings with both partners on the call and frame every deal around keeping the PPOR protected.

03 / Investors

Equity-rich investors graduating from yield to development.

$200K+ equity, sick of passive rental growth. You want manufactured equity and you want to see the feasibility before you 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.

Recent Case Study

The Illawarra site.

A real mandate we ran for a trade-builder couple in early 2026. First development between them. Under contract in 14 days at 4% below asking. Numbers below.

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.

Live Site Briefing Zoom

Free 45-minute call. Both partners welcome. We share our screen, walk you through the Mosros platform, and pull up two to three live sites that match your brief. You see the feasibility on each. No pitch.

ii.

Six-Month Engagement

If we're a fit, we take you on exclusively for six months. Weekly screen-share updates. Direct vendor outreach. Full CDC and DA pathway assessment on every candidate site. Your own login to the Mosros platform.

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
$8,000 + 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
$30K or 3%

$30,000 flat on acquisitions under $1,000,000. 3% of purchase price on acquisitions from $1,000,000. Payable at settlement. No vendor commissions, ever.

About the Founder

Started because the small-developer got forgotten.

I'm Mulisa Ndlovu. I run Mosros out of Canberra, with a deliberate NSW focus — Illawarra, Sydney metro, South Coast, Newcastle and the Hunter.

I started this business because the people doing small developments in NSW — the builder doing their first one, the investor with $300K equity making the leap, the couple wanting to build something together — get the least sophisticated advice in the market.

The big consultants work for the big end of town. The buyer's agents on television sell interstate rentals for yield. Nobody's 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.

That's who Mosros is for. One job: find NSW sites where you can keep the existing home, add one or two more, and the numbers actually stack — before you sign a contract.

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.

How is this different from a buyers agent like PK Gupta or Metropole?+
Different category. Buyers agents generally source yield-focused investment properties — existing houses in growth suburbs. Mosros sources development sites where manufactured equity comes from the project itself, not market movement. We work exclusively with NSW sites and exclusively on KEEP + ADD strategies under LMR and CDC pathways. Different problem, different solution.
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 if my partner isn't fully on board yet?+
Bring them on the call. We run every Site Briefing Zoom expecting both partners present. If one partner wants to develop and the other is anxious about the PPOR or serviceability, that anxiety is legitimate and the deal needs to be structured around it. Solo calls with one spouse are almost always a waste of time.
What regions do you cover?+
NSW only. Within NSW, our active sourcing spans Greater Sydney metro, 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 six 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.
Are you a licensed real estate agent?+
Mosros operates as a property development strategy and feasibility advisory. Any formal purchase negotiation is conducted either directly by the client or through a licensed NSW buyer's agent we refer to at no fee to us. ABN 38 684 626 560.
