Hello BP, My name is Greg and I'm a 30 year old electrical/software engineer from Erie, Pennsylvania just starting out on the real estate/FI journey. 

Currently each unit has their own electric meter and I am thinking about changing the heat system to Ductless Mini Splits for each unit so each unit will pay for the heat they use and they also will now have A/C which will allow me increase rent for that amenity. 

You can outsource marketing (any agent will list it), accounting (any CPA) but without relationship with Tenants you'll have constant problems.Such companies exist - they take phone calls 24/7 and then transfer them to PM to coordinate contractors.If you don't care about your bottom line, you can hire such a company: they will call to the most expensive plumber co, electric co, etc - you pay the money, they fix the problem.Fixing toilet would take you 10 min plus driving, they will call the plumbing company which takes $200 just to diagnose the issue (im not kidding - I've had such thing).

Several times we have found them in the electrical outlets in the bedroom, paid for a chemical treatment for those spots and been fine.

I did have my electrician do an electrical plan overlay for the electrical in the kitchen, so that is one factor.I will also say that there are crazy energy regulations in place in CA that can impact the electrical and HVAC. 

Similarly, one of the houses needed an electrical panel replaced (we found out with the inspection) and once we said we wanted the cost covered by the sellers, he sent his electrician in to get a quote, and wrote it in the contract.

You must be in another part of BC which brings me to my next question - After you've spent the money fixing it up (which, most people will probably agree, you can assume will be at least 50% more than you've budgeted seeing as it's your first experience - and it's probably best if you calculate in a complete refurbishment of plumbing, electrical, perhaps roof or foundation - don't even try to do it piecemeal because it will screw you up in the end), after all that, will there be a GOOD market for resale? 

Gas, electric, water, garbage all paid by tenants who are all month to month.

The sellers recently installed new forced air heat in all the units and the electrical service has been upgraded.

However, check with your local electric company, water company, and city and county.
