I’ve notice on Redfin right now there are a few 2 families that have been on the market for more than 60-100+ days.

Hardly noticeable.

I'm not an expert on California law, but I believe you are allowed to give a 60-day notice of termination for a substantial remodel.

I am serving her a notice to vacate at the end of her lease in feb. 

To protect our rights, we would definitely deliver a formal 5 day notice (Wisconsin Legal Blank), but at the same time indicate that we are looking to collaborate to find a solution.

Tenant stopped paying rent before 2 months of the lease expiring, property manager filed for eviction process but tenant vacated the property before sheriff served the notice.

They filed an eviction on a tenant mid-escrow and withheld information on eviction until I saw a posted eviction notice on the door after closing.

Just what I've noticed. 

JC - I just got the app today after coming across it in this discussion and noticed that (although it's not on the mobile app) the desktop website has a tab to upload a csv file to import entries.

They do, however, have up to 60 days to return a security deposit after a tenant moves out.If an eviction is necessary for nonpayment, landlords are required to send a seven-day written notice of the payment due.
