My home market in Miami Florida is too expensive and cash on cash would not be the best for ROI.

Our tenants SFHs and duplex pay gas/electric so one less bill makes my unit more attractive, I also have less concern of CO issues.The determining factor for me was heat, if the furnace is gas then so is the HW heater.

Someone from Jacksonville - Florida or Miami attending the BiggerPockets' Conference this year? 

I have seen under roof then seen heated space  

That house had a heat pump and the room in question was at the far end of the house, so it was often a bit cooler.

@Tasbeeh Corporan-Francois - sent you a message with a wholesaler that may help in your search in miami. 

As landlords, we pay gas, heating, water, sewer and trash; the tenant pays electric.

A/C and heat is an issue unless you will use a window unit.

Hey BP,In the middle of a rehab on my first BRRRR.Duplex is about 3000sqft and has ducts to first and second floors, but not to 3rd, and needs to heating and cooling options for entire duplex. 

You fix the roof, heating system, electrical etc....This stuff though this is just tenant drama.
