Is someone close by using an extension cord and an external outlet to pirate electricity? 

Whether or not they will...I don't have my license yet (working on that), but given the circumstances of the transaction (not representing an external client, an innocuous mistake based on inexperience with this type of transaction), I'd probably be looking for a new broker if they wanted to charge me more than simple, reasonable expenses.

With as cheap as storage is these days, either locally on an external hard drive or even better in the cloud, there's not a big reason you can't keep the records for years.

I think if you ask most people in the know and see the unequivical data now, it says the worst part of this cycle is now over (short of some other external mechanism causing it to tumble again like Europe, our own Debt Crisis, etc).

I don't think you can take an arbitrary per centage and apply it for such external obsolesence, especially since it may not be preceived as such in the market.Exactly what is across the street?

There really are endless posibilities of external factors and have nothing to do with the roof.

When depreciation begins to fade, when the external property issues of a maturing area begin to slide, I dumped them and moved on.

Then I will respond externally with a response to the other person.I hope this helps and congratulations on moving forward with trying to buy your house.

Here it is easy to look at 20 properties and see which is the best value without a lot of speculation on external factors.  

For this reason some investors stay away from condos but as long as you do your homework condos can also have good opportunities with respect to rent to value ratios (RV ratios) and the HOA usually covers all structural and external maintenance issues.
