Coming from the Midwest, we had been hoping to find an old industrial building or warehouse ideally on a waterway, for easy conversion (5000+ sf base area, 20+ ft height or multiple floors, drive-up/drive-in access), but are clearly very late to the party.

If there is a chance the damage extends into the home into these currently inaccessible areas you might want to ask for a further inspection to areas adjacent to the current damage/infestation. lastly, as a construction business owner the cost for most termite damage repairs is relatively cheap but for a non professional structural termite damage can be a huge expense and should be repaired and treated properly and never covered up as if found out about later legal repocussions could be substantial.

I've found that it's easy to get off track trying to make the system work, look pretty, calculate correctly, print out correctly and still be able to search for a single record in real time during a lead call.If all you're doing is mailing, you can probably get away with Excel files and add a code to your mail pieces for control purposes.I've set up a number of DB's in Access, and must say that the most current version is not very user-friendly and I pretty much stopped using it.I've watched another friend create elaborate list management and mailing programs in Access, however he's a programmer-type who'd rather spend time writing code than talking to prospects.

We replace stoves and dryers with electric, but water heaters and furnaces are generally inaccessible enough that we don't worry about them.

There is camping there, but I think you'll have to check what available/open for when you'll be here, as I think the weather might make it inaccessible, but I'm not sure.There's plenty to see in the LA area - Hollywood walk of fame (where all the stars are on the sidewalk with people's names), Griffith observatory (which I think is open again, but verify that), La Brea tar pits (yes, legit tar in LA), museums, Reagan presidential library, missions, etc. 

We sent another pest control company over they could not find any evidence of an issue, but did say some of the house was inaccessible and they could not confirm of there were pests in those areas.

Termite companies will not spot treat and provide a warranty and (in CA at least) must list a full tent job when issues extend into inaccessible areas as the #1 recommendation.

With the doorway on the back of the house, it sounds like it may make the kitchen feel inaccessible. 

At least near me, which is my limited experience with them, most of those land areas are too inaccessible to be developed more than a 20 ac lot thats completely off grid.

Once it gets into the inaccessible cracks and crevices, the wood acts like a sponge.That said, flooring that has joints is somewhat counter-productive (unless it's ceramic tile that's grouted).
