In Chicago you request a CHA Burden sheet and that gross number minus utility allowance will be what you get in addition to making sure bedroom size is adequate.  

You can also check their reviews online at Google, Facebook, or Yelp.

Does that include utility service to the house, a driveway, septic and well? 

Louis, Memphis, and Birmingham offer a good balance of affordability and rental demand, while online platforms, auctions, and networking with local agents can help you find undervalued properties.

When we purchased our laundromat, it had a strong brand and positive reviews online.

Out of that voucher amount, they will have a utility and appliance work sheet that provides a cost for each utility or appliance not provided by a landlord for each bedroom size.

And via the clustering we are utilizing green-space in a communal manner thus reducing foot-print of that BUT retaining such perception as each unit has walkout to what seems a BIG green space.

@Alecia Loveless is correct--tenants need access 24/7 to their electric service panel, water and heat, assuming those are individual utilities for each unit. 

I've been running the numbers on different properties using a variety of online calculators for properties that I initially thought looked like there may be potential.

Or is it better to utilize different strategies?
