While searching for an investment, build up your team: PRO's like RE attorney, accountant, GC, inspector, mortgage broker, and RE agent. 

We are going to start developing land that we bought across from an In-N-Out as our first development and I would love to hear your thoughts on how we can maximize our investment.Also real estate agents / brokers who have worked with large retail or commercial tenants, let's talk.

Insurance - Talk to your insurance broker.

I was able to reach out to some brokers/realtors in the area and get some really solid advice on how to approach this.

I called a few loan brokers in FL that were recommenced to me and they all told me the HELOC would need to close in an individual persons name.

I would suggest using Websites for information only and to call commercial successful Real Estate Brokers that are well experienced. 

A list broker can run reports to see where the majority of homes sit.

I'm reviewing their management agreement and came upon:Is this a typical compensation clause that most Management/Broker companies include in their agreements?  

Additionally, there are 3 units in this house and they are all leased until June of 2019 - so we couldn't move in anyway.Speaking with a mortgage broker, we were advised that - if we were to use a FHA loan as first time home buyers - for a duplex it would be 3.5% down.

Your offering more broker fee to the broker isn't going to change the owners mind.
