My area is seeing a lot of growth from out of state and thought it would be great to have a nice welcome letter as well as a handbook for specific type of questions (how to use the fireplace, How to use and program the auto lights, How to program the automatic schlage lock, favorite local restaurants, etc) When we bought a home several years ago the sellers left us a note as well as a bottle of wine and to this day we still talk about that for a first impression.

I'd add "curb appeal" to your list of places to spend money (exterior paint, clean up the yard, light fixtures, address numbers, front door, maybe garage door, etc.).

I'm making an app that's like a light version of quickbooks, specifically for real estate investors (you can track transactions at a property level).

Unknown #1: Time selecting finishes.I would start with some kind of template: look here or online about colors that work, flooring and lines of lights and fixtures that will remain as thoughtless decision in the finish selection process.
