Thus, I need someone competent to do a thorough financial analysis to help me understand where the swing points are in the tradeoff where one option would make more sense vs. the other one.Something along the lines of:https://www.nytimes.com/interactive/2014/upshot/bu...but which also incorporated my current investment property holdings.

Good that you bought it as an LLC, because it sounds like a law suit waiting to happen.If I'm reading this correctly, my recommendation would be to encourage the tenants to move, then start over with a new design, making sure to incorporate someone who knows a little about building codes. 

Were the later materials actually "incorporated into the house" (I assume they were not acting in any way as just a "material supplier" so simply buying them and even delivering them without installing them would not count as work).

I'm partial to instagram and wordpress has built-in widgets that allow you to easily incorporate your instagram feed into your page. 

Thank you for the input I'll probably incorporate and have the paperwork finished in about two weeks.

The tax reductions are a major stimulus, which has yet to really kick in. Corporations

My LLC is registered via a 3rd party and my name is not anywhere on the articles of incorporation (as I am trying to keep some privacy but also have that wall between tenants).With this being said, after you transfer your LLCs from your personal name to an LLC, I understand you cannot change the terms of the existing tenants lease, however, is there some sort of short and simple communication I can give the tenants letting them know that the home has transferred ownership and that their lease agreement held up and house under XYZ LLC? 

For example, there has been a plan in place for years now to incorporate a high-speed rail line that extends from Glassboro (South Jersey) to Gloucester City/Camden area and this would give a more direct line to connect with Philadelphia.

But I almost fell out of my chair laughing at that one!

I have a full-time job in corporate finance and am what most people would consider mid-career.
