Depending on the age of the house, even if "fully renovated" it may not have any or enough insulation.

I'm listening to the webinar now and they offer 100% money back so I'm curious how things are going for you?

Is there debt on the property or are you doing all cash?

My duplex cost me $620k and requires only a small amount of cosmetic work2/ With remote work more people are moving to NH because they don't need to go into the city as much3/ Some people are sick of MA politics so want to move to more conservative NH4/ There is a housing shortage in NH. 

Probably a silly question, but I feel like duplexes or more are a little more complicated when it comes to insurance, which is something I never thought about PRE buying the house!!!
