I am in my mid-30s and plan to continue to buy and hold for decades.  Right now we have a rental built in 1954 and another built in 2004.  Am I wrong to be wary of buying a house that is 70 years old?  Or do I just no...

Think it won't effect A and B areas--look at the BMW 7's and Escalades tooling around in the tough neighborhoods (they have more than enough money to spend).Forcing people to unknowingly house dangerous hard to deal with individuals (between prison sentences) is harsh. 

The upsides seem pretty clear -- what are the dangers and downsides specific to car-washes? 

I can drive 3 minutes east and it's D, don't get a flat tire, dangerous. 

Its more important to have the intent correct: ie 'no burning of any substance' to cover smoking then not to have any mention.

Very dangerous when used poorly, but extremely useful when used properly.

This a dangerous approach to real estate investing in an over priced market.

One thing I have to mention- Agents (I'm only speaking from my experience in NY) cannot tell you if a neighborhood is "good" or "dangerous".

I am NOT an expert in construction by any means - I only know enough to be dangerous.

Even a gentle bull can become dangerous just through the sheer power they possess.
