New construction loan newbie question

[Colton Joseph]

Hello,

I have recently purchased a lot for $36,000 that is on the tax roll for $75,000. The purchase was just made a couple months ago, and I am wanting to build a new single family home for myself. My question is what is the max amount that I am likely to loan without bringing any more cash to the table, and ONLY using the equity from the lots as my "down payment." Any advice would be great!
