For some time, I offered the use of our vendors at our rates and discounts for maintenance, and in our management agreements, requested small reserves for maintenance escrow, to handle costs.

I then usually line up all of the major applicant details by qualification category in an excel document (exclusive of personal information) and make a decision based on who is the most qualified applicant. 

@Kent Stauffer  can chime in here, but I would say the market could start to top out at 1700 (larger homes have a discounted price / sq ft).  

Cons: they are nearly exclusively variable rate, some lenders called them due in down turns.   

We timed the market well also - I could see commercial prices still undervalued - and we picked this up at a 20% discount on today's prices - so over $200k in very quick equity gain.

I manage exclusively STR's for residential real estate and some STR's mixed into my commercial property.

Anyone who came back to me with those issues looking for a big discount I would probably dismiss as not a serious buyer, looking just to low-ball and get it under contract so they could then try to get big money off the price later. 

Or would my realtor be almost exclusively dealing with me?

I wouldn't offer any discounts or to cover any other moving costs.

At what volume should a discount be discussed?
