We would have kept it as a rental property, but the condo complex we were in passed a number of very restrictive rules on rentals out of concerns for the explosive growth of AirBnB/VRBO rentals.Here's my take on developing land in Door County:1.

where there this is explosive job opportunities, then explosive real estate follows."  

And a brand new industry was born.Until the late 1970s, Nickerson's book, published in NINE editions and revisions, was the only book geared to the small investor wishing to have a direct investment in real estate.By the late 1970s many people, some just owning a single family home, had ridden the housing price explosion in California real estate, and thought why not do this with more than just their personal residence.  

Then, they realized that this was wasting Time and we have had this explosion of Tear Down and Build new Town Homes etc.

@Madeline Shawcroft  one must be realistic.. the picture you paint Is not super conducive to explosive growth in RE.one suggestion is one of you may want to get a RE license and work part time.. get in the game. it cost about 1k to get that. 

Even surrounding areas are seeing explosive growth. 

Old Irving Park and Portage Park have been seeing explosive growth lately. 

This coverage is in case of something like a natural gas explosion in a rental killing someone.

Coverage: Fire, Hurricane, Tornado, Wind, Earthquake, Vandalism, Vermin, Lightning, smoke, hail, building collapse, Explosion, Leaking water, burglary.3.

There is a massive explosions of developers all around this area putting up new condos/commercial buildings.4 - Central City Mall, this is just an added bonus.
