Just look at how busy a Home Depot is , do you thing everyone is pulling a permit ? 

I've heard of mentees who started cleaning up construction areas on a flip at the end of each work day or picking up supplies at Home Depot and delivering them to the job site.

Also, any experience with extended warranties, if they are worth it (Home Depot wanted $290 for 5 years), and if they are honored at rentals?

I can't imagine maintenance on brand new tiny homes would cost much, especially if you did composting toilets and rerouted any grey water to a garden or something you'd have no plumbing to worry about. 

I currently live in a senior and multigenerational community, original owners from 1980s, we have garden day once a month.

It can protect you when your workers are loading up a work vehicle in a home depot lot, when they pick up the phone while in the office and slander someone etc. 

The materials are part of my renovation budget and I'm paying draws, but they are the ones buying it directly from Home Depot or whatever. 

If I were you, I'd either find another company, or get a trailer and a helper and go pick them up yourself at Lowes or Home Depot.

Some great neighborhoods that have great schools, and low crime in the Orlando area are College Park, Winter Park, Windermere, Winter Garden, Maitland, Baldwin Park, SoDo (south downtown), Dr Philips, and Oviedo. 

We have four bathrooms and rarely use the one on the second floor when compared to the rest.I ran the water about 10-15 minutes a day for a week or so, threw a few scent pellets down the drain (bought at home depot).
