Heat pumps are electric , and when the emergency heat kicks on , its the same as electric baseboard .  

I asked for examples and he said if emergency calls like electrical wiring is loose, definitely get that fixed, right?

You can make it work...just need to have boots on the ground in event of emergency while your on the road.

Just about every contract out there prohibits the client from turning it off except in an emergency.

This creates a higher likely hood of more appreciation, as the properties are still priced significantly below adjacent neighborhoods.I do plan on selling the properties in a couple of years, since the ROI isn't great, and just keeps getting lower the more equity appreciates.I keep an emergency fund if something comes up.I'm still small enough that I can cover losses from the day job in a worse case scenario.I recongnize that this is high risk/reward strategy that isn't sustatinable in the long term.

I'm assuming your $100K is your emergency fund.  

Will you have an emergency fund for your personal situation and will have emergency funds for your business?  

I am in position to pay off with cash with some help from home equity line of credit  or pay off totally with cash and use home equity line of credit for any emergency cash needs for a year to replenish my reserves Need advice to make better decision I am not in rental or real estate business .

Make sure it clearly states how much they can do without actual approval from you as not hearing from you should not be considered consent, but understand that in an emergency like heat goes out in January that they can arrange for repairs if they cannot get in touch with you.  

I'm totally torn between slowly building up a healthy chunk of liquid cash (for investing, emergencies, whatever) or gaining instant equity (and lots of it).
