One thing I realized is that the concrete slab is colder in the winter -- I think my HVAC guy indicated that this is not so great for heating bills.

All units rented outPrice-$110,000 Looks fairly updated so not expecting any improvement costs and purchase. 20% down 30 yr fixedRent -$2270 10% vacancyUsing 50% rule it would cash flow $681/mo Owner pays heat & water1.

With the capabilities to control water, heating/air, doors, and even monitor occupancy; does anyone use automation products in their rentals.  

A tenant informed me the property will not heat above 58 degrees. 

A friend of mine packs some serious heat when he goes and collects.

IMO clear in REALTOR provided contract - that heating/cooling structural electricity are included as inspection items.  

You are correct Steve and to clarify my point is that the cost of waste (which is the fear of most landlords in the scenario) is $100s vs the cost to separate , run new lines, add heating units, add hot water heaters,and add AC units which could push $10,000. 

martins heating and air. only guy I use!

That being said, you obviously do need to have a great deal of knowledge in those areas.I myself have an electrical contractors license, am certified in residential and commercial wiring and have a degree in Heating and Air conditioning and twenty years experience doing all of the above.If you do work in one particular town the municipalities building department and inspectors will also get to now you and see what quality of work you do

.- Verify the existing installation for heating and water heater (new heating system on 3rd floor)- Remove asbestos insulation and pipes in the basement- Verify the existing electrical installation and upgrade to support new appliances- Some windows to be changed and we may consider to change them all depending on pricing- Repair the roof if neededWe are also considering doing most of the work on the unit we would live in (other than plumbing and electricity) but we really need to find a GC that can work within our budget!
