Wondering what the benefits would be to them, if any, on doing a zero interest loan for us.Sorry for not having a ton of details here, this is the first non residential deal I'm doing so not entirely sure of what questions to ask.Thanks in advance.

Additionally, you are not hitting anywhere near your total VA benefits so if this is your first VA loan you can use your second tier benefits on your next place. 

. - Then you need to adjust your expectations or change markets.  

I started holding seminars to explain the four benefits of owning real estate.

There are benefits to doing so, but there are significant drawbacks as well.

Pre-existing conditions are handled differently but you can get scripts for massages, chiropractic adjustments, etc, that are fully covered.

This also has the benefit of reducing liability to our other properties, held under other LLC's. 

  - Has not made any efforts to put it on the market or rent it per my suggestions (may be nervous about being a landlord)Since he is not making any effort to sell I think it could be a good strategy to partner with him to rent and manage the whole process so we both benefit.   

You still get the benefit of their experience and I think it would be a less complicated arrangement.

This includes PAR and NAR fees. you may be able to find a board/broker that does not require PAR/NAR which could save about $300/year but would limit your other benefits.
