To assist in finding homes for flip or rental properties.My question is, would it be legal for me to provide specialized emails (Home photos, ARVs, rehab cost estimates, profit estimates, etc) to my investors highlighting potential flip properties and then requiring that a marketing fee or finders fee is to be added to the initial purchase price of the home If they decide to flip a provided listing?

Gains realized from the investment itself is tax free if held for 10 years but as someone highlighted, you must improve the property by at least 100% of your purchase price. 

Am I missing something or does this really just highlight that the real cashflow is found when you solve a problem with a property, i.e.- forcing equity or rehabbing altogether?

We've compiled and vetted a list of duplexes (about 75) that meet all our criteria and which we'd consider being occupant-owners of.Planned next step is to send them letters stating who we are, what we're trying to do, and letting them know we'd be interested if they'd like to sell.Any experience or suggestions for how to format (handwrite vs typed, etc) and what points to highlight?

@Costin I. is absolutely correct about the DOS clause and hit most of the highlights already. 

Host an event highlighting the haunted stuff. have a dark metal band or weird steampunk band play the event. 

If you choose to get the chain of command involved, understand what you're doing is really highlighting a problem, and not necessarily making leeway towards getting them to pay you...which isn't a bad thing.

When I changed the vacancy rate the monthly cash flow dropped to around $260.Some other neighborhood highlights:- $87,000 median real Estate price- average rent is $1,000 (rentometer said $750 was the average and I have $800)- 65% of the children in the area live in poverty so this is a low-income area. - the main occupations are manufacturing and labor, sales and service jobs
