You'll need to do some market analysis to see what things go for in your area, how you want to handle utilities etc. 

I'd estimate 50% of my investor clients during the past two years utilize professional property management companies and are very satisfied.

Basically all utility estimates were off.

A decent portion of S8 tenants don't pay their portion of rent or utilities - sticking it to their landlord.Forget about using the threat of having their voucher taken away, as that doesn't really happen any more:(We manage almost 700 doors in Metro Detroit with almost 100 S8 tenants.

If you have it in writing that they left, double check all utilities are paid for and transfer them to your name. 

Rent Finder utilizes AI more but both are worth taking a look.

For $295, you can buy a fake identity including id, selfie, tax return, utility bills, credit file, even a phone number where someone will verify employment.

You will also need to factor in utilities as you will be paying those and expect some tenants to abuse it (or not use them wisely). 

Rental demand has been strong with an asking of $1,700 per month per unit that does not include utilities.

There are plenty of investors that utilizes hard money loans.
