Five strategies that fit a 720m² inner-Sydney lot

A 720m² lot in inner Sydney is one of the strategically richest properties an investor can buy. Depending on the LEP, the zoning, your appetite, and your capital, the same address can be five completely different deals.

Below are the five most common plays for a property purchased around $1.4M (typical inner-west or south-east Sydney). Numbers are illustrative — your suburb will swing them.

Strategy 1. Cosmetic flip

Lowest risk, fastest turnover. Paint, kitchen, bathroom, floors, landscaping. No structural work. No DA needed in most LGAs.

Capex around $45 to $60k. Timeline of 8 to 12 weeks. Sale price uplift in the $80 to $120k range depending on the suburb. After holding and selling costs you're looking at net profit of $25 to $45k. Best fit for first-time flippers, or experienced flippers using it as a portfolio filler between bigger plays.

Strategy 2. Full renovation

Knock walls around. Re-plumb. Rewire. New everything. Possibly an extension out the back. Requires a DA in most LGAs.

Capex of $140 to $220k. Five to eight months to complete (DA plus build). Sale price uplift around $250 to $400k. Net profit somewhere between $80 and $140k. Risk is medium because DA delays are real and trade scheduling becomes the killer once the build runs over a few months.

Strategy 3. Subdivision (Torrens or Strata)

If the lot meets your council's minimum lot size and frontage, you can split. Inner-west Sydney councils typically need 7.5m or more of frontage and 250m² or more per lot for Torrens.

Costs run $180 to $320k for demolition, services, civil works and either two new builds or one renovation plus one new dwelling. Twelve to eighteen months. Net profit highly council-dependent: anywhere from $200k to $450k. Risk is high — DA risk, neighbourhood objection risk, build-cost blowout risk all stacked.

Best for experienced developers, or first-timers with patient capital and a town planner on retainer.

Strategy 4. Granny flat or dual occupancy

A 720m² lot in many inner-Sydney councils permits a secondary dwelling under State Environmental Planning Policy (Affordable Rental Housing). You keep the original house, build a 60 to 90m² granny flat in the rear yard, and either hold both for rental income or sell to add value.

Capex of $160 to $240k for the granny flat plus any cosmetic work on the original. Six to ten months from approval. Adds about $650 a week in rent if you hold, or $300 to $450k on resale if you sell.

Council interpretation of SEPP rules varies a lot, so check your specific LGA before you commit.

Strategy 5. Strata conversion

Some inner-Sydney 720m² lots already have an existing duplex or two attached dwellings on title. Stratifying them — converting to Torrens-titled separate strata lots — can release significant value without you swinging a hammer.

Costs around $35 to $80k for legal, surveyor, strata plan and council fees. Six to nine months. Net uplift typically $250 to $500k because each strata title sells for more than 50% of the duplex.

Best if you can find a duplex below market and you've already confirmed the strata path with the council.

How to pick

The right strategy isn't the one with the highest profit. It's the one that fits your capital, your timeline, your risk tolerance, and your capacity to manage the build.

The mistake most flippers make is locking in cosmetic-flip mode before checking whether the same lot supports the granny-flat or strata play at three times the profit for double the work. Or, worse, locking into subdivision when the comp sales don't actually support the build cost.

The right answer is to model all five before you offer. Then pick.
