In general, I'm curious how investments with multiple investors are structured.

I’ve had multiple people contact me and I’m looking for possible solutions.

if so you will need multiple properties - don't believe all you hear about the cash flow in Detroit. 

That said, I can handle it when necessary and have successfully built multiple self-started businesses and ventures in real estate investing (REI).

I am interested in investing in something a bit more passive as I am getting older and, while I love the real estate asset class, I do recognize the need for multiple streams of income. 

I recommend researching the average appreciation over the past 10 years in your target area to get a clearer picture.As you know, in real estate, ROI comes from multiple sources: Home Appreciation:  Reno Appreciation: Value added through renovations or improvements (usually just in the first year).

Quote from @Chris Seveney: @Charlene Kingsnorth have you had an sec attorney also review what you are doing as if you're are having multiple people as part of a loan participating in it depending on the state this could get you in hot water - so be careful  good point Chris some state allow fractionalized deed of Trust mortgages other do not or require PPM like documents prior to offering them..

Taylor sent multiple email inquiries to our insurance provider asking what risks their policy covered.

As you mentioned, it might be difficult timing the sales of each of properties where you can achieve a combined exchange (multiple properties into 1 property / or a few properties).Just a quick note that may be helpful - I work with a group of investors that can help with a combined exchange into a single property and will buy it back once you've found a replacement propertie(s) as the final destination for your capital.

A solid property management team (or maybe multiple PMs if your portfolio is large enough) is a must for out of state investing.
