They've also managed to get the electric meter guy, the postman, the Amazon delivery driver, and a few others. 

You can order some nice furnishings from places like Wayfair if you are short on time, coordinate other deliveries for when you are there.

It's definitely feasible in some areas to see either now or in the future deliveries outpacing absorption.

Also send it Certified, Return Receipt Requested so you either get a signature or a returned, sealed envelope proving you attempted delivery.

I've been looking into opening a space with 6-8 ghost kitchens (300-400 sf kitchens built for takeout/delivery only).

Cheaper than paying for an emergency delivery.

Its a little inconveneient for the tenant becuase you have to go pick up your mail but if your tenant had amazon deliveries or needs an address for employment purposes they can still use a physical address such as the "#A" or "1/2" that you mentioned.

Custom window sizes are expensive and take about 3-4 weeks for delivery.

I'm super keen on recommendations from folks that have used a PM in the area and like working with them; I travel a fair bit, and so someone who is trustworthy, and can even handle the occasional odd request (like I need someone to meet a delivery co. at the property to put a new appliance in) would be superb.Thanks so much!
