I filtered to junk mail, etc.

@Matthew Drouin and many others have good success with direct mail. 

Be sure to follow all formalities, such as sending via certified mail if required.Transfer Rent Payments: Notify tenants in writing that rent payments should be made to the new property management company moving forward.

So, what if the tenant never accept the mail?

Vacant SFH, absentee owner, 100% equityYou send a direct mail or postcard asking the seller how much they want for their property. 

One that I'm getting close (hopefully) to the end of, was a flip that was a public nuisance property with two lots on either side full of junk (like 10 dumpsters worth..)There was great opportunity with the house, but we bought the other lots as well and cleaned them up (as no one would ever buy the house with those lots filled with junk). 

I do SMS, cold call, mail, online, wholesalers, etc.

I would definatley not go back to snail mail/checks again.  

There are obviously other methods such as direct mail, PPL, PPC, SEO but some take a lot of working capital or a lot of ground work or sometimes a combination of both. 

If it's a verbal tenancy, you have to show a practice of collecting rent that the tenant is no longer abiding by (or perhaps tenant shows up, and honestly states they were obligated to pay rent and haven't done so).When the eviction case is submitted, you give the tenants names, e-mail, phone, address.
