Besides trying to find a realtor/agent to provide rental comps, is there a good method you use to research realistic rental rates for areas? 

I'm looking for advice on how to structure a flip deal. 

How do you structure yours?

Value-add from increasing NOI through various methods of increasing income (below market rents, rehab and increase rents, RUBS, etc) or decreasing expenses.

I would recommend a different marketing piece every 4 weeks for 5-7 months from past data analysis, but you should test this out for your market and see what works best response rate wise.Also, when you become more advanced you will want to do split testing and other methods.

Has anybody ever structured a deal like this?  

I’m sure most of you have seen the recent article about the BRRRR method.  

I have 4 properties using this method. 

and how much profit you are willing to take with each method.

@Ryan Ingram,  REI Guard or I think they are now called NREIG is a referral based structure with the Agent having little to do with the process except referring the client.
