Agreed with @Gregory Schwartz, the gifts with a personal touch are the most memorable.Gifts related to their hobbies/interests are the best.I typically land at $50-200.I work with a lot of clients who buy properties that need work, so I usually throw in a Home Depot gift card with a handwritten note.All the best!

I would like to convert them to card machines.

I also get cards and letters every few days wanting to buy my notes and properties that I own.

The tenants downstairs from them dont raise a stink as the boyfriend doesnt have his green card so they're not going to anything to rock the boat. 

In order to make it worth her while you will have to answer both questions to her satisfaction.To answer the first issue of not being real to her, I use a tool I call flash cash.I will bring 1-5k with me in $100 bills and when overcoming her first objection, “I don’t want anything to do with it,” I will fan out the cash like a deck of cards and say, “I know this doesn’t feel real to you, but I am actually here to give this to you.”

The site allows for tenants to pay via credit card.

I recommend arriving at least 10 minutes early (depending on the event/venue) and bring business cards if you have them.

HOWEVER, you've got to be very vigilant on running the LLC as a true company - separate banking accounts, credit cards, books, corporate records.

How are you collecting a deposit, or putting holds on credit cards, for your STR direct bookings?

Its all such a house of cards.
