Dry wells are required to "store" the rain water on your lot from all impervious surfaces for 24 hours, including the driveway! 

Maintaining it is fairly simple also, after each tenant moves out scrape the caulk from around where the tub and tile meets and the corners and re caulk, make sure the caulk matches the color of the tile to blend. replace the caulking every turn to make help prevent the caulk from failing and letting moisture into the wall behind it, if it molds then eventually your tiles will start popping and you will have to tear it all out and replace wall and tiles again. if the tub gets worn down or even as i have saw in the past extremely dirty when no matter how much cleaning you do the grime wont come off just sand it with a fine grit paper and home depot sells a resurfacing spray kit for around 60$ and if you take your time will take about 1-2 hrs then 24 hrs to dry and will look like a brand new tub.

It's waterproof and requires no underlayment (or even moisture barrier in dry climates like ours).

Let dry, repeat.

Longest part would be drying in between coats, really.

Lot slopes and trees can mess up your day as well as soil quality and proximity to waterways.3) Permits and what order those permits are required4) Budgets - the more accurate you can be before you spend, the less hair you will pull out.5) Financing schedule - getting the money isn't so hard as spending it properly.

It was an iffy property that barely met my standards, but I wanted to make a deal (it'd been a 9 month dry spell).

the money dried up.

It has to be kept dry.
