My first experience with a special assessment is with a condo we lived in, the HOA fell behind in paying for electricity of the common area and gas for central heat.

Water heater, Electrical, furnace, AC, etc.... 

Maybe it'll work out for you but having negative cash flow bugs me even though my wife and I can afford it. 

Electricity is separately metered on all three.I contacted a mortgage broker.

one tenant said she has bed bugs, we sent pest control for 3 times, and didn't find any bed bug, he called city, and city said even he caught bed bugs some place else and placed into a jar, and showed to the inspector in the apt, we have to do a bed bug treatment?

they are ok thank God.I did a walk thru of the unit yesterday and took them some bug spray trash bags case of water and sprays to just give a helping hand.  

It is a garage in the back that has plumbing and electric already run to it.

Real estate kind of went by the way side as I was working different jobs and building my electrical business.Last year I was working at a home that was in rough shape when the neighbor told me it was for sale.

We do have electricity.

Water, sewer, trash - on the owners, tenants pay electric and gas.Judging by the rental price per unit in 2011 ($540/mo per unit) it has a lot of deferred maintenance.
