Super short term loan needed

[Donivan Norton]

I have a client needing a short term loan to finish a rehab. By short I mean 60 to 90 days and about $30-50k. Credit cards are tapped out due to projects, score alright but affected by that (low 600's). Loan to value on one house is 47%, 68% on the other. Trying to avoid messing with the existing first mortgages as they are great rates and terms. Any suggestions on Hard 2nds or unsecured loans?
