I've noticed it's super uncommon not only in Slovakia but in Europe to rent a house.

I have talked with the county (planning & environmental) informally, read the zoning/etc code and the shoreline master plan, and asked around for recommendations as best I can, but these SMALLER projects are uncommon.

Therefore I didn't provide much other than a proverbial kicking of the can to get more info...Wrap around mortgages are fairly uncommon in general and back in 2012 when he "bought" the property they were virtually non-existent. 

I’m looking for uncommon ones...I see a lot of people on here that are agents,inspectors,contractors...I’m wondering what other cool jobs people have gotten because of their in depth knowledge of real estate and investing.

Lastly Ill assume you have the land under control in one way or another and that other due diligence has occurred regarding environmental, title, etc.The next step for you is going to be find a local architect to put together a feasibility study to confirm you can get what you want out of the site this often happens prior to purchasing the site so if you are in the middle of some of the things above that's not too uncommon, you just want to have it under control in one way or another so that you don't have the site bought from under you while you are doing this. 

So there answer is it depends but generally speaking yes there has been a lot of competition for MF properties in Denver over the last few years so it is not uncommon for properties to sell for over asking price and cash purchases are also not uncommon.

What are some uncommon ways to do this?

It would be uncommon for someone to purchase a property, however, knowing their only access to it was by boat. 

This is not uncommon.

The money is made developing a set of uncommon skills and leveraging them to make a substantial profit.
