So no house.  I’ll skip the full output, but for the tipping point I see:
 
irb> (x..y).select {|n| puts "#{n} #{(x..(n-1)).sum} #{((n+1)..y).sum}"}
 
355 61610 62060
356 61965 61704

I went a step further and figured out the equation to solve the puzzle. 
Implemented in Ruby:

irb> range_sum_midpoint(1,8)
=> 6.0
irb> range_sum_midpoint(50,500)
=> 355.6332380416656

The equation itself is left as an exercise for the rec.puzzles reader.  :-)
