Using your $100K example, the 6% seller assist is far more valuable to this buyer than merely reducing the purchase price by $6K because the 6% seller assist is a $6,000 reduction in funds required to close whereas reducing the purchase price by $6K equates to less than a $200 savings (2.5% down payment + some incidentals).

An example of this is I had one trash company that collected the same three containers for $90 less than the in place trash removal company. $90/month X 12 = $1080 increase in NOI, at a 10% cap rate that small change increases the value of that property by a whopping (1080/10%=$10,800)!

For example, John down the street bought that house for X and put in 30K, and then sold it for X.

I have past examples of people I've helped in all cases. 

For example if there is a Starbucks there, typically there can't be a competing coffee shop in the same plaza. 

A good example of this might show high return for a house in Detroit that is 100 years old, next to a GM plant, vs lower return for a 10 year old house next to the Tesla plant in Taylor, TX.   

Something problematic they find that was undisclosed on your application (not saying you'd do this, just giving an example), title issues, entity issues, issues with the appraisal even if the value is acceptable...you can either bite the bullet and pay for the appraisal, don't move forward with the loan, or try and find a HML/PML willing to lend to you without an appraisal. 

For example for me, CoC does not matter as I buy in A/B areas and I hold long term so I am comfortable knowing even if I have zero a slightly negative CoC to start over the long term it will turn and I will end up with a nice return after many years. 

Main questions should ask about the seller's:- Reasons/Motivations for wanting to sell- Desired timeline to close- Plan's after selling (relocation, reinvesting proceeds, 1031 exchange, etc)- Back-up plan in case they are unable to sell within the desired timeline- Reasons for not already selling to/with a investor or RealtorAdditional questions will depend on the type of seller lead i.e. pre-foreclosure, probate, fsbo, absentee owner, etc.Here is an example of a youtube search you can use to begin finding call recordings.There are 1,000s and you'll find that the best/most effective ones don't even sound like sales calls.

For example, if your old tenant moved out November 25th and you place a new tenant 15 days later, then you can hold the old tenant responsible for 15 days of unpaid rent.4.
