Also, my PM has recently started taking rent payments by debit and/or credit card.  

I was just hoping somebody would have some insight into this process and maybe some words of wisdom so that I can protect myself against upcoming renters that have their rent prepaid and deposit taken care of.

You forget the prepaid insurance and taxes.

The PDF is emailed to me and the tenant.Intuit Payment Network checkout screen: Simply checkout screen that charges $50, paid by credit, debit, or bank ACH transfer.Once I get the $50 payment, I send off the PDF to NTNonline.com, and they give me a report within 48 hours.If you're curious about GravityPDF, you can try their demo here:https://gravitypdf.com/#GFdemo

I have capital lined up to buy properties, but I am in need of a partner to help get the first deal off the ground, meaning someone who's willing to put up the down payment and prepaid interest.  

Curious, why would a debit card take 1-2 days versus ACH at 5 days from the same account?

Erentpayments is more flexible in that they offer various debiting options which can vary the frequency and day of the week.

Chris A. my card is a bank issued debit card for my business account.

When I cancel the policy they refund me whatever I have pre-paid for the month. 

They ask you to increase your credit card limit in huge amounts to fund these packages or pay with debit.
