I'd also add to that that you are paying a 20% withholding tax on gross rental income. 

I have been working with investors in my area and partnering on deals for the last 4ish years.

thanks everyone @Edgar DuarteI would suggest you research “return on equity”.  

Although I've considered a future line of credit against the property as my best long term option, I would need to pay down the remaining balance first.

Nobody likes being left in the dark when you’ve got money and time on the line!

I have a few rentals with section 8 tenants, and they tend to stay on average 4-5 years.

I think I've talked to maybe 2 tenants on the phone so far, and I didn't mind because there's a lot of scams online.

Truthfully, I am not that big on coaching programs BUT, I can understand the benefits of having someone in your corner teaching and coaching you on the ins and outs of real estate investing every week. 

Most, if not all, can be found on You Tube. 

Give them all the details, contact information, time lines, relationships, etc.
