How do I do cash for keys?

[Elias Barend Westhof]

So we have two tenants in our fourplex in los angeles. We want to do a large remodel, but because of rent control the only option of removing them is to pay them $22.000 each in relocation fees. We were therefore planning on doing cash for keys, but I have no idea as to how to go about this. What do you guys think? How should we go about doing this? Do we just go to them and tell things as is? 

Thank you for all replies!

I love California where Tenants have more power over your property than you do.
