You would want to look for an owner that has a loan through a bank or credit union or one that has no mortgage. 

am working with them now and had the first policy (with Spinnaker) cancelled for nonpayment/late payment so we rewrote another policy (with Millenial) and having the same payment problem again but at least they are communicating that cancellation is coming. they want me to pay by credit card over the phone so the payment wont be late and cancelled again. but when i go to mycoverageinfo.com to check on status it shows its been paid.

The internet as wonderful as it is has also created a 'wild west' effect that is often unbridled.  

And your credit will be ruined for like 7 years.

Yes, that’s another credit union only asking for 10% down with no pmi.

Reports to credit bureaus.

Of course credit card is going to be like 3.5% but it does kind of such because it's already hard to get tenants to pay it lol. 

Most local banks and credit unions will have free accounts.You need two accounts: checking and savings. 

If your interest payment is $8,125Your stocks have to make a dividiend of about $11,000 of which you would prolly pay 15% to 25% in federal / state taxes / NIIT.Assuming you will make a 10%-11% return is not guaranteed.You will also feel good about having a paid off property(relief).Furthermore, your credit score may go up with a paid off property.Best of luck!

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.
