How many doors do you need to hit your target?  

However if you have enough reserves, 6mo or greater then I'd say chance it but a couple of missed payments from the tenants and you have to foot the payments out of your own pocket.I'm all for taking risks but I think you really need to evaluate the age of the major systems so you don't get hit with a bunch of cap ex all at once as well as your reserves. 

First, I’m not really seeing enough cushion in certain popular areas for investors to realistically hit a 30% profit margin.

I am an aspiring serial house hacker based in southern New Hampshire actively searching for my second small multifamily deal in the Nashua area, but I've hit a wall with inventory being so tight in my local market.

Airbnb is supposed to take the hit, in the case of a natural disaster or storm etc. 

I just wasn't sure if it is my responsibility to do something if the electric bill is high and are not satisfied. do I have to be concerned about that?

My big bold move was to rent them at $150 month with tenants paying for heat and electric. 

Many properties will need specialized attention, especially with plumbing, electrical, and historical elements. 

there's people out there who will fund downpayments for equity in the deal or a preferred return. hit up local meetups and facebook groups and have some conversations

Electric heaters are dangerous and can start a fire if left unattended.
