Possible off market deal - HELP!

[Kellyn Cameron]

Hi everyone - 

I have a potential off-market deal and I need some opinions from more experienced investors. 

I met with the seller and they told me they would prefer not to list it on MLS but would if they didn't get the offer they wanted. Well after talking for several minutes they told me two numbers. The number they would list it for if they went to MLS and the number they would take off market. The off-market number was about 6% less. When I run my numbers at this price I come out with about 8% coc roi. My goal was to get 10-12%. While we were talking the seller also mentioned that is possible in the next several years they will be looking to sell off numerous other MFHs.

So... my question is do I offer the number that meets my goal of 10-12% or do I offer what they said they want, take a little less return in hopes of creating a relationship and possibly having a chance at more of their properties in the future. Obviously, they might not accept either offer but I'm totally new to this and just wondering if anyone has some advice! Thanks!
