I’m also looking for C/C+ properties, ideally in the surrounding texas tech area. 

If you want more risk, I'd just sort them about by C-C return.

We offer 4 different payment methods to our tenants: Online ACH via our PM software (no charge) Deposit @ our bank ($3 charge) Credit Card ($5 + cc fees) Mail ($10 charge)Notice we charge a fee for the less desirable options to encourage the behavior we want:)Please send us any feedback via email, as we do not use the DM feature here.

Some really dedicated people online that tell you how to maximize the use of a cc

Once all of this is done, you are putting all of your living expenses on a credit card, so from day 1-28 of the month you have no money actually leaving your accounts, only extra debt being racked up on your CC. 

What are the best areas and location in Buffalo to invest for C , C+ to B- neighborhoods?

@Tim George I will say this...no STR, unless you are in CC proper, and even that can be a risk.

That doesn't mean you actually have to spend them assuming you can either carry contractor payments or you have other options for items like CC for material purchases etc.

CC debt ?
