One thing to consider though, that most people don't realize, when you higher and pay for an architect/engineer to do drawings you get to count that money spend as improvements to the building when it comes time to get your commercial loan.

Or getting into commercial? 

What are some effective strategies for attracting commercial tenants to my property beyond listing on LoopNet?

The value in this type of commercial is in the leases.If you can get approvals for the apartments, there is value in that.

Based on your inputs, I think simplifying to a single management company and starting with a single holding company makes sense and then I will add additional holding companies as my portfolio grows.Nathan - on the $1m in equity per LLC portion, would you split properties up into separate holding companies based on type (e.g. residential, commercial office, commercial ag, etc.) or would you keep multiple property types in the same holding company as long as it's under $1m?

Is an estoppel certificate something you want to do only for commercial properties or should you also do it for residential ( duplex, Triplex, quadplex)

I have already built a geodome that is commercially permitted and kills it so I'm very familiar.

A commercial property is depreciated over 40 years.

I’m currently reviewing a fully occupied mixed-use commercial building with 8 SRO (Single Room Occupancy) units but have never dealt with this type of property before.

There are however recorded covenants against commercial property.
