There are of course numerous other ways to market to off-market deals like FaceBook, Cold Calling, Google Adwords, Driving for Dollars, Networking with other investors/Realtors, Bandit Signs, etc...

I was considering asking tenant 1 to sign an addendum to remove tenant 2 from the lease and make them the only person who has 'occupancy'. 

I questioned this date, before signing the purchase offer, because we needed to move in ASAP, and the ad stated ASAP and the seller's Agent assured us he had already purchased a home and MOVED OUT. 

You will just end up backing out at the first signs of trouble, saying, "I told you so", and not going back. 

I know that it is my fault for missing this clause in the deed before signing so I accept that responsibility but my question is does the title company or realtor have any liability in this matter? 

When we bought the first house, we signed a 15 year, which we are currently 5 years into.

Lindsey,Assuming they are joint obligated, it is generally the total income of the people signing the lease.

Given that there are a few properties of this scale for sale like this around the south seattle area (and a very well kept 16 unit in renton that I think didn't sell and the listing expired recently too)  all of which are similarly overpriced and havent sold instantly,   Its another sign that maybe things are peaking,  or at least stabilizing. 

What I do know is that one of the many, many things signed by a buyer at closing is an agreement to keep the property insured and authorizing mortgage companies to put insurance in place and bill the owner-and those rates aren't cheap.

If you like the deal get it signed up, pay EM to YOUR attorney and then you can find out if he really has the property or not.
