Should I buy 2 plug-in baseboard heaters or add baseboard heaters wired to circuit breaker box.

If you turn the main breaker off so everything in the house is dead there is no need to check for live circuits (still good practice to check though). 

Nothing would be a deal breaker alone, but factor this level of expertise in when evaluating the complete picture.For example, a big problem that I've seen is if a single tenant building is applying with a regular lender, sometimes they apply a vacancy to their own DSCR (Debt Service Coverage Ratio), and they apply a vacancy factor for a single tenant building, which is just wildly inappropriate.

I would also speak to an electrician about installing GFCI Outlets on the first outlet in a run that will ground the rest of the outlets in that room/circuit.

There might be more notices to tenants/city necessary permits that are mandated in CO, but that's probably not deal breaker worthy. 

She was declared guilty but appealed to the Circuit court and lost but then appealed to the State Appeals court and the court remained it back to the Commission for further clarification/prosecution. 

I want to know their goals, what their deal breakers are, and what their long term plan is.  

The key is to educate yourself on these issues, understand how to spot them, understand why some of these issues might (or might not) need to be remediated, and understand how they can be remediated--and the costs associated with remediation.The only issue that is a total deal-breaker for me, personally, is major structural issues (e.g.; major settling, serious foundation problems)...but even then, there are investors who specialize in buying and fixing those types of properties --again, the key is educating yourself so you know what you're getting into. ...it sounds as if maybe you're looking for a hard-and-fast rule like "DON'T buy a property with X", or "DO buy a property with Y"  --the reality is, REI is rarely, if ever, that cut-and-dry--it has many shades of grey, and it requires flexibility and creative thinking.Good luck!

That makes me think if this should be a deal breaker or not.

That would definitely be a deal breaker.
