How Much Deposit Do You Need for a $700k House?
How much deposit for a $700k house in NSW: $35,000 with the 5% Deposit Scheme, $70,000 at 10% with LMI or $140,000 at 20%, plus income needed.

The deposit for a $700k house in NSW starts at $35,000: an eligible first home buyer needs that 5% under the 5% Deposit Scheme, with no mortgage insurance and no transfer duty. Without the scheme, a 10% deposit of $70,000 usually carries LMI, and $140,000 at 20% avoids it. Registration, conveyancing and inspection costs come on top of every route.
| Route | Deposit | Loan | LMI | Transfer duty |
|---|---|---|---|---|
| 5% with the 5% Deposit Scheme | $35,000 | $665,000 | $0 | $0 for an eligible first home buyer |
| 10% standard loan | $70,000 | $630,000 | about $15,000 to $23,000 | $0 first home buyer, $25,687 otherwise |
| 20% | $140,000 | $560,000 | $0 | $0 first home buyer, $25,687 otherwise |
What does $700,000 buy in Sydney?
Usually a two bedroom unit or a townhouse in the middle and outer rings, or a house in the outer south-west and north-west. At this price the first home buyer duty exemption applies in full, so the duty column is $0 for eligible buyers, a saving of $25,687 against the general rate.
Could a house and land package get the First Home Owner Grant?
Yes. A $700,000 house and land package is under the $750,000 cap for the NSW grant, so an eligible first home buyer could receive $10,000 as well as the duty exemption. The guide to house and land package loans covers how lenders handle the land and build stages.
What income do you need?
| Deposit | Loan | Single | Couple |

Is a 5% or a 10% deposit better at $700,000?
If you are eligible for the scheme, either works without LMI; a bigger deposit lowers the loan and the repayments. If you are not eligible, the LMI on a 10% deposit is roughly $15,000 to $23,000 here, so it is worth checking a guarantor or a professional waiver first; see low deposit home loans.
