Security deposit and interest requirements

[Tamas Z.]

Hello,

What are some of your standards on how much security deposit you collect for your commercial leases? Is it something based on credit score, e.g. "fair = 3 months rent, good = 2 months rent, very good+ = 1 month rent"? I'm not yet calibrated to what's considered pretty standard, though I realize it really changes case-by-case, depending on other improvements and things that are part of the deal. But suppose there's no such special provisions, what's a good baseline?

Also, I believe for residential, you have to pay interest on the security deposit when you pay it back, but am not finding any info about whether that applies to commercial leases as well. Maybe it's a state-by-state thing, and I'll definitely look into it, but maybe there's just a blanket law about it that someone here knows. I'm in WA, btw.

Thanks much!
