Just got a call from a tenant , no heat .

I had an electrician address a problem with my hot water heater, he fixed the wiring, but referred me to a plumber to replace the heating element and thermostat.

Back in 2014, I purchased a multifamily that was flip for 317K, I put in 40k into the house (finish basement, central air and heating. 

Lastly, even if there was a fool proof method to estimating all your expenses, there is no way to predict the human element.  

My builder thinks the units are small and electric heating should not be an issue.

If the heating system craps out and you have $0 in reserves you have a serious problem.Is Waterville mandating fire dept inspections yet?

I've always been hands on (currently own or co-own 12 units) so will be relying on a property manager (feel very comfortable, currently manages property and is VERY reasonable - referred by my broker whom I trust)3) Concerns - it is rural; sewage is septic; plumbing is crawl space and exposed a bit to the elements. 

I would need to take a hard look at things like the fireplaces since there are 7 and I know in old properties sometimes they are not up to fire code. possible asbestos though the heat is radiant and it has central air, possible lead piping, and possible new electrical.

I mean, if you just go to one contractor and say build me a kitchen, you take out the element of competition.  

Question: The unit has radiant electric heat in the ceilings.
