@Robert Horvick as others have mentioned, 10% down may not be feasible if you are not planning to live there.Also, make sure you are budgeting properly for capex - a flat percentage of rent won’t necessarily cover a new roof or furnace if either need replacing in the first year.When analyzing a deal, don’t adjust your numbers to make it work as you stated.

We've obviously considered additional apartments (most expensive) all the way down to storage which is basically free.

Others find creative ways to make extra Income by renting out extra storage spaces or the garage.

Local industrial property, zoned for self storage, is hard to come by to build or convert.

I am buying a mixed use property with 30 self storage units and 15 apartments.

I literally worked in all aspect of real estate accounting from Office, Shopping Centers, Condos, Affordable Housing, Luxury residentials, development/construction, property management, hotel/motel, self-service storages, commercial, and some others.I worked for Trump as well.15+ years of experience in real estate accounting.

Walked in with equity; however, I also added storage racks and electrical updates.

Someone tell me this is feasible!

You should spend the extra 10-15 hours per week reaching out and networking with General Partners of multi-family, self-storage, and industrial syndications while educating yourself on how syndications work. 

I would like thoughts on how to finance (we would need approx. 200k) building a duplex (a barniminium with half storage half and 2 -2 bedroom apartments).
