I am thinking in running a mail campaign to hit some deals off market.

At the time I was running on direct mail.

Many small businesses that are home based need a business mailing address and the use of meeting space and an occasional office. 

Perhaps combine a direct mail campaign with your text message and cold call campaign.

I’m relatively new to wholesaling, and I’ve been diving into the process—cold calling, direct mail, and driving for dollars.

We allow Tenant Portal (ACH), Direct Deposit to our bank, Venmo, Strip (credit & debit cards) and old-fashioned mailing of checks. 

Surely this could be an issue with the foundation of the house soon.I reached out to the builder twice by email and once by certified mail and there has been no response. 

The rent checks are mailed a few days in advance of the due date.

I mailed a 3 day to pay or quit notice, obviously nobody was there to receive it.

@Karen Seguin, it all depends on what you are trying to convey to your tenants.At minimum, any welcome letter should provide updated contact info for maintenance requests and mailing address for rent payments, and if the legal notice address is different than lease, include that.This can also be a good way to politely remind people of any general rules that you expect them to adhere to.
