There is a right way and a wrong way to conduct business. 

No one will invest with you or work with you if you don't have a track record as a successful real estate investor, entrepreneur or business person in the past.Then, you need to get educated on the apartment syndication terminology and process so that you can communicate effectively with team member and investors and understand how to find, evaluate, submit offers on, conduct due diligence on, and asset manage apartment deals.

A company that is reliable and knows when to be there will be the biggest challenge.Once you have a few potentials in place, give each of them a call and see how they conduct business. 

Repairs and upgrades should be conducted as necessary.  

In fact we have a 3-Day Developer's Academy that we conduct once a year, most recently this past summer 2018.Please feel free to PM me and I'll give you some quick insight as to a high-level approach (as in the 30,000 foot view) to what you realistically need to do to determine if it's feasible and how to do some financial forecasting on the "back of a napkin" to see if it makes sense to move forward.Please note that Developing a Self Storage Facility from the ground up can certainly be lucrative. 

Hey Yaz,I saw your post while conducting a search for "green building" within Biggerpockets.

In Bridgeport, CT the investment is about 10% of rents collected which frees you from taking resident phone calls, coordinating maintenance, leasing vacancies, bookkeeping and accounting P&L's, conducting inspections and making property payments.

Income from conducting a business would go on a schedule C, and would qualify as self-employment income capable of sponsoring a Solo 401(k).  

In Oregon, even though you are licensed and can conduct your own sales since your license is hung with a managing broker (Oregon term) they have to review all documents for all their agents within 7 days.
