At your suggestion, I went on an looked for Tri-State REI and Tri-State RE and not so surprisingly, there are groups for both in the area.

In the future, if possible, I'd suggest putting the tenant on a payment plan with a deadline and once the payment plan is signed sending that to an attorney.

Any suggestion on any free websites that I might be able to do that? 

A simple DSCR (rent/PITIA) calculation can be an easy way to evaluate the property if you are doing that type of loan.

It’s as if you gave the money to every contractor who suggested a repair. 

Maybe you should consider selling your SFHs as some have suggested and trying one larger multi family with a full time property manager who will give you month end statements and end of year reports to give to your accountant at tax time.

Make it simple on yourself.

This is my first investment and planning to invest in multiple properties over the next 5 years get financially independent. please suggest good markets to invest in midwest. i am currently looking in Kansas, Iowa and IL.

We have a very simple proprietary profit/cost calculator for fix and flips.

Otherwise do what @Dustin Tucker suggested.
