Door lock, detector batteries, other consumables, replacement of damaged or disappearing items like pool towels and linens, replacing blown out screens (I spent over a grand just on screens last year though we did have a freak huge hail storm).

Well, I am an electrical engineer that builds batteries for electric vehicles.  

The other guest was a long term stay and I had to replace batteries in the door lock.

For example, the tenant didn't replace a single light bulb or the tenant took the batteries out of the smoke alarm...it seemed it kept going off when they were smoking apparently.

Quick answers here:- modular can be cheaper but it really depends on the builder and the only places I've seen consistent cost advantages in cast are in really high cost areas because you're essentially outsourcing half of the labor (i.e. building the modules) to lower cost areas - financing is a little more complicated with draws for modular being earlier so only some lenders deal with them, but you should be able to find lenders who do underwrite modular on similar terms to other constructio lenders- appraisals are typically pretty similar and homes tend to hold value similarly, but it probably depends on the quality of the build

It's built in a factory where controlled conditions produce more precise measurements and better over all fit of modules than is possible when stick-building on-site by hand.

It's a big enough city with plenty of land so one day I wouldn't be surprised to see it snag something big like a car factory, battery factory, chip factory, etc. 

Platinum-grade batteries with a three-year warranty, brake pads guaranteed for life, windshield wipers changed every year, Michelin tires changed every 2 years, oil changed every 5000 miles.

It's on the corner of main and battery and they have shuffle board...Not sure how busy they will be but maybe with the holiday it might be lower key.

I personally thought the program was good and I got through all the modules within a week.
