I came across an RE opportunity that seems too good to be true but number works.

Good wholesalers will price deals well, meat on the bone for you.

Is Phoenix a good market?

I'm totally good with some sweat equity but I'm not in a position to do Roof, siding, structural repairs and such.

If any of the houses are in a good enough shape to still be usable as rentals, you would sell as a rental property as that will get you a higher price.

I would recommend you begin researching Chicago based meetups as there are a bunch of really good ones.

Any referrals or recommendations for good and qualified brokers, sellers, property management companies, loan brokers, insurance brokers, mortgage brokers, contractors, etc.

Seems pretty good to me. 

Looks good.

On the flip side, if you've got a bunch of Section 8 tenants living in a building that's in a neighborhood where a lot of the tenant base has good jobs, high credit scores, and are generally reliable people, you've got the most risky tenants in that tenant base and that ain't what ya want.
