I think it's difficult to find customer of a fired out property .

At a minimum, I'd like the website to generate leads, tell customers about myself, and collect rent.

Derek really highlights the problems here as well as potential paths forward well.

One of my best tenant/customers is a guy who draws a military pension and purchased a property from me on seller finance terms, I was willing to finance it for 10 years to make payments around the same as what rent would be, but he wanted to only carry it 3 years to pay off fast.

For example, does the ad highlight the main features, schools, walk score (walkscore.com)?

Flipper A put in $100K of work and put in all the necessary accoutrement that would attract the customers (walk in closet, open concept, Jacuzzi bathtub, etc.) and is selling it for $275K. 

Speaking of loans thought I’d let everyone know that the bank that I had in mind for my cash out refi is no longer offering loans without seasoning periods to new customers.

You can email invoice that has the link to pay online or auto-draft customer's bank (free) or credit card (3%-4% fee).

Customer service is nonexistent and when I finally did get a hold of someone it was the rudest woman I've ever talked to. 

They're pretty available, can probably pick a blank up from a big apartment complex and customize to suit your needs.
