Staging is very important for most buyers because it helps them to visualize living there and inspires them to strongly consider making an offer.If they have to guess whether or not their furniture is too big for the rooms,they will error on the side of caution and quickly move on to the next house.If you are selling a lower cost home in a working class neighborhood,go to a rental furniture center like Aaron's and the like and ask for a quote for a monthly contract.You will find having them deliver it and decorating yourself will save you a ton of money.

Also, the property was not delivered broom clean as stipulated in the contract. 

You should absolutely, positively have a reputable title/escrow firm (preferably local, but not necessarily), do a title search, however, you can do that after you have submitted your offer, and the seller has accepted, as in the contract, it will stipulate that your purchase will be contingent on the seller delivering clean title.  

I bought a new black plain jane GE fridge for 448$ delivered and they take the old one for 15$ .

If however the tenent can be gotten rid of by the existing owner I would ask if it is possible to be delivered an empty building, go in, and do your repairs, and then find your own tennent, and rent to them on your own terms.

So if we have a list of 10,000 phone numbers, 4,000 will deliver, and we'll receive roughly 80 calls.

had to submit 4 other counter-offers (all were 30 day, cash only, as-is deals) before winning the final bid (and offering that I would fully cleanout the property.. it just had to be delivered empty). 

@Mohan P.A property should be delivered to you in the same state it was when it went under contract, so you should not close until the seller repairs the damage.

It's always good to deliver what is promised.

I obviously want the property delivered vacant, but if the Seller is eager to get out, could this be an opportunity to take on his problem and get a great property at a discount?
