Hey BP,In the middle of a rehab on my first BRRRR.Duplex is about 3000sqft and has ducts to first and second floors, but not to 3rd, and needs to heating and cooling options for entire duplex. 

I prefer to stay somewhere in the middle of both.Make sure to also pay attention to the other fees (underwriting, equity placement, guarantor, asset management, construction management, etc). 

Additionally, does any one have any tips for posting as a Referral/middle man kind of job.

Thank you @Matthew Choi and @Ivy Flowers I really appreciate the advice.

Let's just say you can get middle of the road rents at $1400 per month. $1400 (rent) - $950 (mortgage)- $140 (property management at 10%)- $98 (7% vacancy rate)- $70 (5% maintenance)- $70 (5% capex savings)= $72 a month of positive incomeMy goal is at least $100 a month of positive income per door.

@Ivy FlowersHey ivy!

I still do business with the guy I chose that had the middle estimate.More recently I ended up using a guy that also came in with the middle estimate for drywall, because the lowest estimate cancelled out the night before the job was scheduled.

I would build a wall in the middle and install 2 roll up doors. 2x the rent.

I am a new house flipper in Milwaukee and in the middle of my first project.

Whereas a mobile home park in the middle of nowhere may go for a 12 cap because investors require a higher return for something that is much more management intensive with less appreciation potential.One might assume that a higher cap rate is always a good thing, however, if your business plan is to force appreciation by improving NOI, a lower cap rate multiplies the value of the improvements you made more than a lower cap rate based on the simple math of it.
