There are also a couple brokerages like ours that offer flat rates.

I am not seeing a vacancy rate (maybe baked into the gross rents).

Have you run multiple analysis on this deal considering worst to best case considering at a minimum all of the allowances that i.e. are baked into the BP calculators or some comparable tool?

Flat out.

I would try to make it work but I am emotionally flat. 

The wholesaler/buyer is using a flat fee online service to market on MLS.

The percentage that you're referring to (which I'm assuming was in response to my reference to it) is just what we tell our clients that they'd have to pay you, the investor, as a good faith earnest money deposit.I'll only be charging a flat $300 fee for bringing you a tenant-buyer.

Now in Attorney closing states you can see private attorneys do this for less might have a flat fee and don't junk fee you to death.. but that's rare in my markets I work.For RE brokers I get it though I mean I started selling land at 18 for 2,500.00 to 10,000 per parcel we made 10% commish..  

Our plan is do build easy 3 story 18 Plex garden walk ups on flat, RM zoned parcels in the Willamette Valley.

Bought a 3 flat + non conforming last year in Wicker Park and this year was able to get a 2 flat and rehab it in West Town.
