I now feel like I have a straight line and can finally move forward.

Hosting a website through Squarespace is relatively straight forward and cheap.

I am considering posing this as a zero interest deal, so the $72,000 ($2,000 x 36 months) paid in the 3 years leading up to the balloon would go straight into the principal, and so will the $17,500 down payment.

You have to know with 100% certainty.And even then, an HOA can/will change the rules overnight, and they usually do not get less restrictive.Go to the next BOD meeting and ask them straight up.

During this whole time I mucked around in tiny crawl spaces with mouse crap and snakes, cleaned sewage off of myself more than once, made at least two emergency room visits (one for drilling a hole straight through my hand installing cabinet knobs), sweated my *** off in attics in the summer.

You may want to see if the limit for the Building increased or if it is just a straight rate increase. 

It's so straight forward you will be like, "this is really pretty easy".  

I've wondered if for example it even makes sense on a NNN retail building.Maybe if your CPA can do it cheap as part of their tax return service fee for you.Hopefully just your normal straight line depreciation is the way to go, but check with your CPA and see if they think it is worthwhile for you.   

When I sense issues, I go straight at them.

Sure, many may try to hold margins but very rapidly competion will drive them straight down.
