The feed back I have gotten from potential tenants is that CRM has a difficult application and showing process.

I am not confident how much it would cost and wonder if it is wise to pass this property to fix if I am not familiar with this issue.

I found out who did it for them and the cost was 1/4 what they charged at the workshop.They also offered a deal, but I didn't feel ready .

Mine currently allows weekly rentals but it's driving insurance costs high.  

Once you start changing the rules because you get good or bad vibes from a potential tenant, you can get yourself in serious hot water and end up in court for a fair housing violation. 

That’s means this one claim for under $2k after your deductible could easily cost you $1,000 or more per year for the rest of your life.

I believe the primary issue is the 20 year term on a typical commercial loan.My current focus is on buying and hold duplex properties, and around me that put the total acquisition costs around $200-250k, with total monthly rents being 1.0-1.3% of the purchase price.  

Are there any other potential ways I could construct the deal so that I can do 1031 exchange without tax implication while still be able to exit investors?

It kind of depends on what your goals are, but you may be able to start consolidating your properties a little more with like-kind exchanges and/or purchasing larger properties where you could do cost-segregations on.

extra cash down saves you interest, but costs you the opportunity to make money with those dollars otherwise.
