Seller motivation, condition of property, comparable sales, etc.  

So I recently posted about trouble I was having when two of the room mates on the lease demanded to be let off, the other two wanting to stay and two more wanting to be added.

I am unfamiliar with the real estate market in that area and I have a few questions:What is the level of demand of Duplex or Triplex?

I came across this probate home which I think can have great potential, how do I go about finding the seller if the owner died ?

I think the only way to "make it work" in LA is getting a good deal, ie. spotting houses that have been on the market for a couple of months and then negotiating with the seller the purchase price.

Experts agree that a "balanced market" (meaning it's neither a buyer's nor seller's market) should have an inventory of 6-months. 

A seller may tell you it's in a B class area but for that price I highly doubt it.Although Milwaukee is a great city with a lot of potential, there are many bad areas also. 

If you go to closing with a loan package, it shouldn't make a difference to the seller as long as you close on schedule.

The seller is asking 600-620k for it.

This is my second deal, and here is a general outline of what has happened:Mid April: I put in offers to buy the rental property.Late April: Seller accepted offerEarly May: PM/ seller dragged their feet through availability for inspections/ appraisal.
