When you pay off a mortgage you pay the interest for all the years you didn't own the house?!?

Long Term non-paying Tenants.

The property owner's tax professional can help them with that and ensure they don't pay taxes twice on the same income.Disclaimer: My advice/opinion in this post is just that, my opinion.

People in 1981/1982 were angry they were paying 18% interest.

Our current mortgage terms include a late fee after 5 days, so they’re already paying extra each month and have to split the total monthly payment up between 2-3 payments when they get their pay check.

Some PMC's will charge a lower percentage fee, but will charge it whether tenant paying or not.

My net number is rental income minus expenses(3 mortgages, paying power bill at all three houses, property tax, insurance, internet in two properties).

Expect to pay 4.5% once you account for village, town, school and county taxes. 

I reduced my responsibility to only taxes/insurance while the tenant buyer does the maintenance, pays utilities and makes monthly payments to me. 

If you truly are limited on time or can't make investing a priority, you should look for smaller projects as others have recommended.1) General Contractors are available to run your project, but most are too expensive to make ROI work on smaller projects. 2) A great PMC can act as a Project Coordinator for rehabs, but many won't be transparent about the costs, so you know what you are paying for.
