If a person tries to sell you a house based on pictures and descriptions, it can be a hard sell.
On the other hand, if they show you a finished house it’s much easier to understand what it looks like and how it might be the perfect fit.
When possible, consider building a spec to show a finished project. When this isn’t possible, consider building some type of a prototype to make it easier to see what the finished product could look like.
Have a great day!
