raising funds for developing - non - mortgage options

[utopian99]

Will post this in start ups too but thought I'd try here. I have my own architecture practice, and dh and I also do small scale property development through it. To date this has been buying properties for between £80-140k with a mortgage and selling at an average £15k profit after refurb etc., but we're also looking at land, and Un - mortgagable property now. Ideally we'd raise finance for this rather than use other investments for cash purchases, but I'm new to this side of funding - bridging loans or business development loand or something along those lines. Each project is typically 4-6 months from completing purchase to completing sale.

ANY suggestions for fianance options that aren't mortgage based? This would allow us to buy similar things at lower prices as we'd only be competing with other investors in the non - mortgage brackets. .
