There was also an issue posted recently about Cozy and if the tenant uses CC they can use the CC to fight a payment, and Cozy takes the rent back from you etc..... do a search.

Also, you could use StayFi to collect emails and they automatically import into Constant Contact and then you can set up automations through CC.

And while I'm at it should I always CC the co-signer for everything, even late notices or is it a case-by-case situation?

Tenant I inherited turns out to be a fraud and been using stolen bank and cc to pay rent.

Sure it's slower but you get to learn way more and have 0 risk(unless you add CC/debt).

Doe shaving it all on one CC make it Easier to track and maintain expenses?

To be fair, the seller's agent did cc my agent in his email and he did attached a detailed calculation in excel spreadsheet.

It's the cities that border Detroit that you can buy: (General Numbers, can provide PDF reports and example properties for specifics)- B-,C+, C, C-,  Neighborhoods- 3 Bedroom 1 bath 1,000 sqft- $50k-$85K purchase- Rent $800-$1200- Very Light, Light, or moderate rehabs- ROI (12%-18%)- $200-$400 cash flow per door. 

One of them was CC the other was a referral.

My business is 100% referral after 20 years.When I started, at 23 yrs old, I put a paid mentorship on a cc.
