Never built one, if its straight driving range the cost is in the land as the only equipment is the machine to give the golf balls, the balls and the tractor to pick them all up. 

Do you remember how much it ended up costing?

Flex prepays (stepdowns, etc) are available but will cost additional bps.

Sam - did you ever find a more cost effective solution to this than SaniStar?

So, you may want to call the assessor's office and talk to them about your "theoretical scenario" (rehabbing a place to add a bathroom and room, but not adding to square footage) to see if/how they would re-assess.

Do they still come with high closing costs?

Keep in mind that a property in Spain on average costs around ~180.000.

This was on KSL as well and the sellers were very very motivated.This year I have also purchased two single-family homes that I am rehabbing and both allow for lot splits so I will have a renovated home to sell or rent and a free and clear lot with each one.

The costs out way the benefits especially with these higher rates. 

You should literally be talking about peanuts here, water and electric with no one using them shouldn't cost hardly anything.
