Realtor in the process of purchasing my first duplex - advice plz

[Alexander Quan]

Hi Biggerpockets world!

I am a realtor looking to purchase my first duplex. Property has two units that can be rented out for 1800-2200/month. There is also a garage that was converted to 3 units with tenants paying $400/m. The property is in pristine condition. The zoning is Multi Single Family -2 to 4 units. And is in an area with lots of renters. The price for the property is $680k. We gave the asking price. There are 4 offers total. The sellers want to work with me and my fiance because we connected but they said if we offer $705k then they will accept our offer and not have to do a multiple counter offer.

What I thought about is that I will offer $685k and give my $17k commission to the seller to make up the difference. I am not sure if this is the best approach and as this is my first property that I am purchasing, what would you do? Is this even a good deal?

My mortgage will be around $4200. Please any thoughts and advice?
