HELOC or creative line of credit

Hi.

I am looking for a smaller, around $50,000. line of credit to be flexible for down payments, construction cash, and/or just to have in case of unexpected repairs. I have each property in an LLC and my primary in a Land Trust. I have run into issues with getting financing because of the LLC or trust. I am in Illinois and could use advice if anyone has had luck with a particular company and these circumstances. I tried Aven, Figure, Discover, Fund and Grow.... HELP! Thanks, Jessica
