Maybe other investors never offered 75K or the seller never accepted a lower offer before , but is now willing to after 2 years of being stagnant.

I never look at the property until a get an accepted offer.  

Example 1: A loan above a consumer usury rate of interest, with a 1 year balloon payment at interest only payments monthly, secured by a pledge of income from other business operations or sources of income and with a pledge of life insurance being required can be acceptable in a commercial loan transaction, all of these aspects are predatory to a consumer.Example 2.

In most cases, both short-term and long-term postoperative pain was acceptable.

They may accept less, or it may go for more, than the listed price.

To the extent possible, the Baseline Standards will leverage off of existing standards or generally accepted business practices.

On a couple of deals I've closed this year, my offers were I write the Sellers a check for a net amount and I pay all the closing costs, unpaid taxes, lawyers fees, title, etc.One property is a 10,000 s.f. commercial building that was listed at $90k and I originally offered $50k that was accepted.

Say if I were to win the auction and get an acceptance from the bank on my bid/offer, do I become responsible for it? 

These properties will require a group deciding if they will accept your offer or if they will have another sale with these properties. 

They are still getting back to me on what they would want, personally I don't care what they want for the property if it doesn't fit my threshold of an acceptable deal, 2. but realistically thinking of Cap rates and what could be done to increase the value of the property once bought.
