It heats the whole room by 15 degrees every 10 minutes. 

One of the sides was already occupied and rents for $800/month, we pay water and heat.

also I always thought the big island with some of the sub 200k SFRs would be good you don't have heating systems or airconditoning to worry about like on the mainland. just an idea.

great to hear, by the way, man its cold here right now, lets hope we get a heat wave soon

This will keep the tenants from griping about no heat or hot water at midnight.

My question is, is how can I lower the heating cost(make the tenants pay) and let the tenants individually control the heat between units?

For that reason I believe rent prices are starting to heat up and I think will continue to heat up.If people only bought in places where they got the 1% rule then there would be a lot of markets out there where people weren't buying, which obviously isn't the case.

It sounds like things have gotten very heated. 

This is a pro & con, because depending on the property, location, etc. this may not be ideal.The VA has more strict inspection criteria for the property and will not provide a loan if the property is not habitable.  5 major things they look for are structural issues, pests, security issues, electrical issues and heating issues.I know this is a lot to consider, but if you want to dive into the details of any of these items, please feel free to reach out to me in a private message and I'll help explain things further.In my opinion, the pros by far outweigh the cons. 

For example, I replaced a furnace that was old and acting up in the fall because it suxs to not have heat in the winter in Ottawa (where that property is).
