Property Investment plan needed

I have $90K equity in my house, and $80K investment in a vacant lot of land.All up, not that much really – $170K equity. The loans are with 2 different banks. The lender for the vacant lot won't let me draw equity out, and will only let me lend to build on the land. I am desperate to get into full time property investment, and I know a fair bit about property, but not much about financing and investment strategies. We are limited to one income at the moment, and so we are not really attractive clients to a bank to lend money to. I am not sure if they would even lend me the money to build on the vacant lot due to income at the moment. Perhaps I should shift both loans to one bank? Would this give me an advantage? What I want to do is form my own company, and employ myself and other half (somehow) to work full time on property developing, (hence borrowing a little to live off while doing my first project(as I think it would be better than slogging away at the job i have now) I really want to buy, renovate and sell, or buy and sell, preferably without selling our house (as we need somewhere to live anyway.)I feel confident enough in choosing a project which I could make a profit from and i know alot about Council , planning, potential of homes and vacant lots(planningwise) and construction as we both work in this field. I have been asking around for investors, but I can't find an investor for at least a year, and I do not want to wait that long. I am ready to move now. Does anyone have any ideas about where I could start and if its possible – i.e do banks consider this type of idea if I put a proposal forward to them(forming a company and employing myself)?? I thought perhaps I should sell the vacant lot, and use as a deposit for a reno. I am not sure, and wondered if any poroperty investors had some ideas, or the name of a good property invetment advisor who has had success with their own investment portfolios. Thanks for the help and words of wisdom.
