One they fixed (AC not working), the other they got to a barely acceptable state (hot water and pressure).My favorite part related to the conference was on shuttle to the airport. 

It feel outside of my scope of my business model.A few suggestions:- List on CHBO corporatehousingbyowner.com- target a niche market like students, travel nurses, flight crews (if you're anywhere near an airport), and construction teams- if you have 2 - 3 bedrooms, explore renting monthly by room - roomies.com and bungalow.com; you'd be surprised at how many people are on a budget and will roommate with strangers. 

Earlier this year, I helped a client who acquire a 5 bed / 2 bath house hack deal just south of the airport that she is netting about $500 / month on after PITI and expenses.

I'd also speak to the owners of the adjacent properties to find out if any of them have interest in this lot.

We actually put one in our lower level and while this is fine in the summer , in the winter in the northeast this is adjacent to a bathroom and the bathroom is then freezing. 

This project spans over 49+/- acres and features 50ft, 60ft, & 70ft lots, adjacent to a large lake that will serve as a stunning community amenity.

I have no development experience but 2 clients have built permitted ADU's in adjacent LA (90047), and both were under $130k, with your quotes a 800 sq ft ADU would be $200k. 

For example, could this potentially be a cash boom opportunity within the adjacent areas such as Kenosha and Mount Pleasant where one could buy low, sell high within a relatively short amount of time through appreciation, or would the presence of Microsoft increase cash flow in those areas?

The location is prime—adjacent to a college that has experienced 37% population growth over the past five years.

If you’re near the Newark airport you can set up a pilot crash pad.
