Basically, the PA Constitution has something called the Uniformity Clause.

To my surprise a deputy sheriff answered the door in his uniform.

Interview a handful of lenders, not necessarily for rates (which will be pretty uniform) but to find a loan officer who is willing to work with you and your situation to find the best option and will be available and prompt during your purchase.  

There are people who live in cities despite the cost and the crowds and people who live in the burbs live there despite the sprawl, traffic, and uniformity.

sub too Cons for seller:   .... buyer flakes and leaves them not on title with a loan still in their name .. buyer is ripping rents.. seller has to litigate to get title back and make payments lest their credit gets trashed... and in Texas were the bank can sue for a deficiency judgment this can be devastating to a seller..Seller trys to buy another home but cant since this mortgage is still in their name.. etc etc.Very Risky for seller.... and there are a lot of fraudsters out there that just flat lay away a uniformed seller.

But I have some hope when I see a young woman emerge from the woods near my home with her Wendy's uniform on and head out to walk to work each day. 

Like so many things it would be helpful to have uniformity! 

In Las Vegas Class A properties tend to be in subdivisions or communities with HOAs and have a well groomed and uniform appearance and in the best school districts.

according to Carl  the owner of the Oregon shop  these have to be approved at the state level first you know the uniform building codes .. other wise you cant get financing on them. 

I am thinking about, a randomized trial.  1000 yellow letters with MD and 2000 yellow letters without it.Once you start negotiations half of the uniformed contacts should be told you are a Medical Doctor.Profit is probably the most important thing to observe but other results such as... 1)  Call back rates.2)  Number of counter offers.3)  Percentage of increase from original offer to accepted offer.... would be very interesting.PS  Congratulations on getting the MD.
