@John Pickowicz there are tons of members here on BP that exercise the syndication model.

This is good for you as this opens you up to being to find a CPA outside of your state.Your profile also mentions that you are a real estate agent - You want to work with a CPA who will understand how to best reduce the taxable income from your commissions.Home office, MLS Access fees, E&O insurance, mileage, business gifts are a small sample of business deductions available to agents.Best of luck in your search

And the leasee might not exercise the Option to buy, which is great because I keep the house.

Using median home values from even a few years ago to gauge affordability was useless in this exercise.  

Doubt if you'll suffer any hit.You approved the sample.

We have a lockbox where the technician can let himself in anyways, but this little thought exercise has me curious.

Written by attorney investors, it's full of practical advice pertaining to management of investment property, has sample forms that can be edited, and - most importantly - they tell you what your primary state laws are and where you can read them.

Has anyone had any mortgage company exercise the due on sale clause or am I overreacting?

The whole point of my convoluted exercise :). was to get you into at least one lake house with the 1031. 

I ultimately discovered a few sample lease agreements online.
