CONTEXT-(30k in credit card debt, split between 4 cards, mostly in charged off status)(one vehicle loan that was charged off, is now caught up to current, not paid off, 50k original loan amount)(some card companies are contacting me trying to make a deal, so likely only have to pay 20k of debt off.

My assumption is that all tenants have an interest in keeping their cards close.

Credit cards are an "investment"? 

A heloc is an open end mortgage or in simple terms its a high risk credit line similar to a credit card that sits in 2nd lien position adding another trade line to your credit and reducing DTI.Just like a credit card if you ever miss a payment on any debts on credit or if your scores drop unexpectedly they bank can close or reduce your line of credit.

The guy messaging me says he will be the primary person of contact and be paying with a credit card for payments.

I've tried using greeting cards of various colors, using off season stamps, hand writing the letters, using colored paper, and even putting photos of projects I've done. 

You might spend $3000/month or more mailing post cards, and making a ton of phone calls, or just driving for $.Buying from many wholesalers is risky. 

Pretty unreal.At some point, this house of cards will collapse.

Same thing for cameras: I like old style trail cameras with a memory card (for rural properties personally) but if you have wifi onsite, or if you're willing to sign up for monthly fee (services for $5/month and up) the ones with a sim card are getting really affordable nowadays too. 

I just pulled out my debit card and said, "Here you go!"...
