I compromise at X-1/4% or X-1/2%.I do review the services I provide and sell value before discussing commission.There are a couple of statements that I keep in my pocket:1.  

I think this would be valuable in that I won’t have to compromise my job.

I'm hoping i will be able to negotiate a compromise.... fingers crossed!  

as soon as you compromise your criteria, you will get burned.

Quickly responding to tenant requests and maintenance needs), FLEXIBLE (Keeping in mind extenuating circumstances, willing to think outside the box, sometimes compromising, looking for a win-win), FIRM (Exhibiting the qualities of a strong leader and keen manager, strength and resilience when faced with a tough situation, enforcing the terms of your rental agreement, knowing landlord-tenant law better than your tenant and teaming with a top-notch attorney when necessary).Sounds like you are on the right track.

What I did get him to compromise on was the financing.

Use all resources available and don't compromise on your numbers.

When you allow other entities to accept payment for you, such as a bank or an online "gimmick", you compromise the eviction process. 

But, more specifically to attept an answer at your question, I'd suggest simply borrowing enough the one time that it covers the down payment on the four properties...or maybe a compromise where you borrow enough the first time to purchase three properties.

Hey Rafael - thanks for the input, no offense taken...a little back story: I found an investor to buy the seller's remaining inventory 15 months ago for 4.2MIL, which the seller declined...since then, prices have dropped further, and now the seller is willing to take 3.3MIL...but now my investors are only willing to go as high as 2.4MIL, which he delined again...so the frustration comes from putting real offers into the seller's hands, and him balking waiting for the "pie in the sky" deal...he could have been done with this 15 months ago had he taken the 4.2, where now he would gladly accept that...problem is, market changed again, and he's not being realistic...so believe me, I did concern myself with the seller throughout this whole process, trying to get him the best deal I could, while still being fair to the investors...seller just seems to have unrealistic expectations, so my thought was to now see if I could go straight to the bank, and see if they maybe could help "convince" the seller to take what is being offered...you know, maybe hearing it from another source might strike a chord...in any event, since I started this post, the seller seems to be a bit more willing to discuss and compromise his position, and we are scheduled for a call in a couple hours with both potential buyer and seller.Keeping my fingers crossed...Thanks for your honest opinion...
