couple of thing I'm not sure for I understand right in your design, are the closets in the lower two bedroom 1 FT wide ?

It will be really important for my first contact via mail to set the right tone and leave an imprint in their mind to remember me when the time comes to sell their home.When you say high impact design, are you referring to the general aesthetics of the postcard and the look of it?

My favorite FAVORITE parts of the new design are the "stickies" at the top and bottom of a forum thread.

I realize branding and website design are not everyone’s forte, but considering the intermediaries feel completely justified taking a 10-20% cut to host a one page property profile and send in a tax form for you, it seems logical for many STR owners to try and redirect repeat guests to a site you own and control directly.

IMO home warranties by design are effectively worthless.

Keeping construction costs down and design are two very important factors to making $ in the Portland market.

Most of the sites I have looked at/ created a design are running me about $2.00-$2.15 (order of 200) per sign before shipping. 

However; the job is going to depend on the type of house, complexity of design (are you using trusses for the roof or does it require framers to build it, etc., are there utilities to the property or do they need to be brought, is it on septic or sewer, and many other variables.

and is the hardest and fastest worker I've ever seen) and sister (who is also amazing at fixing things and design) are going to do the repairs in exchange for half ownership. 

Dumb, maybe, but architecture and design are in my blood and like you mentioned, to some of us there is more to it than ROI.
