Unfortunately - my current lot for my primary is 1 acre and VERY sloped, and close to a water source (creek), so the county has not even allowed me to permit my downstairs finished basement without an extremely costly renovation to our septic (over $60,000, and that doesn't count demo'ing and replacing our driveway to get to the existing tank and leachfield), and even if I could permit it, it would essentially need to be a treehouse in the redwoods due to the slope (not a bad idea though, I would actually love a livable treehouse on this lot!

How is water, sewer, electric and hvac distributed and located?  

For example, I have a subject property that has 1682 SF on the main floor and 810 SF of finished basement (the majority of which is about 8 feet in height with the exception of some bulkheads to hide the mechanicals) and 271 of semi-finished basement that is a utility room basically (washer/dryer, freezer, hot water heater, furnace, some storage).

I would also look at the availability of public water and public sewer, if not at the site how far away are those services.

Just starting to ever so lightly tread into the water....

Why not start with a small turnkey rental property and test the water?

He used to troll these waters for suckers very hard until I found out that his claimed experience and transaction history was fake.

Meanwhile that water bill growing.

However, most tend to get very watered down with sales pitches etc.
