thanks everyone for your suggestions and i dont think a lot of people really got what i was saying i wasnt saying we were running out and buying a house straight away our goal is 3-5 years time when i have a full time job, plus my business on the side and DH does also work but its seasonal and he has another job when the off periods.
Moving costs dont cost us a thing the great thing about DH being a furniture removalist we have never had to pay to move.
I'm not being defensive here im just getting my point across that it is actually realistic with our time frame etc.

As for MIL we are already on a rental contract we have a lease with a real estate, rent gets paid to the real estate etc but MIL still refuses to fix things if we go to VCAT we are out on our asses and i dont want my kids to have no roof over there heads, as for renting somewhere else that would be too difficult in the area we are in there are only 7 rentals within the district one being here with it being rural it doesnt leave much and we dont want to leave the are DD1 is settled in school, DHs job is only 5 mins down the road etc.

Right now whilst I am on centrelink payments and DHs contract for this season is near the end (hes not doing his other job until after the twins are born he wants to be home to help me out) yes it is impossible which is why we arent running out and buying but asking for tips and advice on ways to save so when that time comes in a few years we can say ok we have well over the 10% recommended deposit we are hoping to have around 25-30% which yes is a lot but can be done and thats all i was asking for was help on how to achieve this over a period of a few years

Anyway sorry for rambling sooky kid and heat dont mix today
