Need more details. ie why is your mother being evicted for another tenant's leak? Did she refuse to pay rent due to the mold issue? No matter what route you choose to seek help - do it asap. Ignoring a landlord's intent to evict is not a wise decision.
Under California law, the landlord is required to return the security deposit (and/or send an accounting of any portion withheld) within twenty-one days after the date the tenant vacates. According to recent caselaw, If the landlord fails to return the security deposit within this timeframe, she loses the right to keep any of the security deposit and therefore should return the entire deposit.
Keep in mind that none of this is "automatic" and you likely will need to go to court to enforce...
More info would be required. However - nothing is going to restrict the landlord from serving the notice. The real issue is whether there is a lawful basis for doing so. After the three day notice expires, your friend will not be "automatically" evicted, and (absent certain extraordinary circumstances) the authorities will not force you out of your home. The landlord must then proceed with an unlawful detainer, at which point your friend will get to make their case before the court.
The law does not require an initial walk through. However, pictures taken by the tenant prior to move in or during move in showing previously damaged items will certainly be persuasive to the court, and may serve the same purpose of a move in inspection.
It is likely to be more difficult for tenants to prove fraud or mistake sufficient to rescind an undesirable lease if they intentionally elect to forego the landlord's invitation (or recommendation) to conduct appropriate prelease...
Absent any provisions in the lease agreement that provide otherwise, the new owner will assume the rights and obligations of the previous owner, and the new owner will be subject to the pre-existing lease to the same extent the previous owner was.
More facts would be helpful. I don't completely follow your description above, but it appears that you entered a lease in 2010 with a "landlord" who was foreclosed upon in 2009. If this is true, the "landlord" had no rights in the property to convey to you and the lease is not valid.
In any case, prior to eviction, you must be first served with, at a minimum a three day notice to quit. At the end of this three day period, the owner must then file and serve an unlawful detainer. You...
Generally, the lease is not affected by the short sale, and you can continue to reside in the home for the duration of the lease. However, if you are renting month to month, then absent certain conditions (including harassment), the landlord can legally terminate the lease provided proper notice.
I am unclear as to what your question is. Has your manager threatened to evict you? Without more information it is impossible to directly answer your question. However, as with all disputes, make sure to keep detailed records of all correspondence and communication, including date/time, general subject matter, parties involved, etc.
The landlord can generally enter the premises only following 24 hr notice to tenant or w/o notice in case of emergency. Assuming the lease does not specifically provide for dates/times when the landlord would like to enter the premises, the tenant does not waive his right to notice.
