The Trulia heat map! 

Beginning in May, she began complaining about the heat.  

I believe the current fix is to crimp on pigtails to all ends and replace the old switches and outlets... varies but think it is running $2500 to $5500 per house to correct... aluminum vibrates when it gets a little loose causing resistance and then heat.. hence the problem.lots of homes have black pipe or steel pipe water lines used a lot in older homes and it is OK but it rusts inside and then as the corrosion continues the pipe gets weak at the joints mostly and often can fill up  and restrict water flowall this being said I have seen extension cords run behind finished walls,  I have heard people removing 40amp breakers and replacing with 50amp breakers because the 40amp keeps tripping.  

So we used the High Heat type paint for grills and such and painted the interior black, and just closed the damper and told the tenants that the fireplaces cannot be used.Another option is that you can have them capped off at the top of the chimney.

In your area heat thunderstorms humidity etc.

That's why an online auction can be a good thing if you are able to participate because you don't have the heat of the auction with others around you at the time.  

The secondary markets are heating up as well.

Then with the combined heat running unusually hard for 5 straight days the heat pump took a dump.Until this point I used similar numbers to you (I actually only kept $4,500 in reserves for repairs at the time).
