You'll likely need to be in a C/C+ neighborhood to find the 1% rule, but you can still break even or sometimes get some slight cash flow in the B neighborhoods of Columbus.

I offer an online payment portal to submit rent payments via ACH or CC - they "couldn't figure out how to use it" so I set us up to accept Zelle payments.

That is a 3.4% cash on cash return in year one (7903/232000)Year 2, reduce 7903 by 5592 because there won't be property tax break so that is $2311, or 1% c/c return in year 2 (2311/232k)Year 3, reduce the $2311 by $4930 for PM fees for a net loss of -$2619 per year or a -1.1% c/c return in year 3 (-2619/232000)Essentially, these numbers are so far off of pro forma and there is pretty much zero wiggle room on these numbers. 

CC payments are exempt.Q4: I pay with Venmo, CashApp and PayPal.

Also CC a copy to the tenant for their records.

The tenants enjoy using the interface, it is simple to communicate with them as a whole or individually, collect rent payments and see when they are in transit, offer CC payment options at tenants expense, track maintenance request, share documents, and lease the property.Short comings are their financial portion.

I would like to explore the possibility of getting my first property in CC custome built.

Have your parents call the company, tell them you were not authorized to make this purchase, and they want it refunded or they will dispute it with their CC company.

See if you can roll anything into zero interest cc and knock off the higher interest stuff.
