To give as an edge we look at a specific matrix Like U-Haul moving statistics, state record (1000 people a day move to Texas) and what has already approved to be built (Toll roads, Grocery stores, housing tracks, and roads) We have several Ag properties, HWY commercials and access to a plethora of off market potential purchases (pocket listings).

She'll thrift or go to estate or consignment stores for the heavy stuff; couches, dining tables and chairs and use a checklist to place one or two orders of ALL soft supplies (linens, towels, rugs) online or major Marshall's runs.  

For example, a $135 dining table chair on Wayfair I found at a restaurant supply store for $65.

These are auctions that sell returned items that can’t be resold in the stores.

They also usually are more energy efficient as the water is heated as needed and not heated to store in a tank that might not be used for many hours and tanked heaters typically have heated more water than needed (and this is desired because running out of hot water is a bummer).I do not want an annual maintenance effort as large as descaling a tankless water heater at my rentals.  

For reference on flooring, I had the local big box store come out last year for a quote.

Virtually walking a property is a recipe for disaster.Honestly it blows my mind that someone will spend hundreds of thousands of dollars on a home  (probably their largest investment) and never visit it, but will run to the store to try on a pair of pants for $30...

Buy a vacant piece of land close by and offer to store his stuff for free until the house sells.
