One of my favorite ways is by going to your local plumbing/electrical/building materials supply houses and speaking with the counter person(s). 

Vibration can be caused by loose pipes banging on the studs or it could be from high water pressure.

Unfortunately, there is no right answer.....It depends on the specific property, it's condition and what you're planning to do with it.For example, on a distressed property that you're going to flip, if it's listed for $250k, I have offered $150kOn a prospective primary residence that is a custom home, if you offer $650k on a $750k list price, the seller will probably just reject your offer and not even counter.

On the other hand, not dealing with roof, pipes etc damage is a big deal for me. 

How can I get over the counter tax deed list.

This meant higher water costs and more strain on the piping.

I have also placed cash offers on bank owned properties and have been denied or countered dollars under market value. at this point why not buy off MLS, closing with title, less risk. any advice?

My guess is your electrical is grounded to your copper piping (pretty common) and you have some sort of trickle charge running through the system and grounding out through the concrete.The other option could be your gas line.

Was gonna be 5 grand to excavate and fix, but luckily we were able to put in a laundry pump and bypass the underground piping for a lot less money.
