From direct mail to cold calling I feel like there are many dead ends is that usual?

Once you have a good sample size direct mail is pretty cost effective.

Security deposit has rules, and in my state, I have 15 days to return the security deposit together with interest if otherwise required, or the landlord shall have 30 days to give the tenant written notice by certified mail to the tenant’s last known mailing address of his or her intention to impose a claim on the deposit and the reason for imposing the claim.If the tenant doesn't pay the rent for the last month, then I would issue the 3 day notice to pay or quit.

Hi @Avery Heilbron, thanks for the reminder.

My Stat Agent then forwards all mail to my UPS address here in CA.

I use a MOVE IN/MOVE OUT CHECKLIST I downloaded from ezlandlordforms that I leave with the lease for the tenant to complete and mail back in the first week. 

If you PM your email address I can it to the group email list so you can get the reminders for the days we meet and and updates if we change location. 

Put your best mailing address too because they occasionally have to mail you things.

In reference to @Peter Walther post about foreclosure, the following is copy & pasted directly from the State Bar of Wisconsin Form 11-2003 Land Contract:"Purchaser agrees that in the event of a default in the payment of principal or interest which continues for a period ofdays following the due date or a default in performance of any other obligation of Purchaser which continuesfor a period of days following written notice thereof by Vendor (delivered personally or mailed by certifiedmail), the entire outstanding balance under this contract shall become immediately due and payable at Vendor's optionand without notice (which Purchaser hereby waives), and Vendor may singly, alternatively or in combination: (i)terminate this Contract and either recover the Property through strict foreclosure or have the Property sold by foreclosuresale; in either event, with a period of redemption, in the court's discretion, to be conditioned on full payment of the entireoutstanding balance, with interest thereon from the date of default and other amounts due hereunder (failing which allamounts previously paid by Purchaser shall be forfeited as liquidated damages for failure to fulfill this Contract and asrental for the Property); (ii) sue for specific performance of this Contract; (iii) sue for the unpaid purchase price or anyportion thereof; (iv) declare this Contract at an end and remove this Contract as a cloud on title in a quiet-title action if theequitable interest of Purchaser is insignificant; (v) have Purchaser ejected from possession of the Property and have areceiver appointed to collect any rents, issues or profits; or (vi) pursue any other remedy available in law or equity.

I have been working on direct mail marketing campaign.
