Cost segregation utilizes the MACRS approach.

I have done extensive research in the risks, how to structure such deals to mitigate those risks as effectively as possible, and legal considerations of each strategy. 

1.To extract equity in your property by re-mortgaging if you brought the property with a mortgage is normally not possible, it might be if you have extensive building improvements. 2.Getting a mortgage on a property you own 100% of is usually possible.

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.

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.  

If the didn't do that then they have converted to LTR or MTR rentals at a steady monthly income and have the tenants take over the utilities which offsets the loss of more income.

@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. 

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.

You can also tell her to call the utility company about the best way to save, as turning off heat and on is not efficient having to run longer blasting out cold air as opposed to leaving it set at a lower temp. :)

I can only speak regarding structuring the deal as I have not utilized partners personally but it really can be anything that you want.
