There are many different cities that are great that could still be considered the gem that is hidden.

Yes this have happened to a property I managed before and it was galvanized plumbing hidden behind walls.

The house I'm working on right now ended up getting 700-800 sq feet of unplanned new flooring (plus removing of that 700-800 sq feet of glued in laminate flooring) and a rebuilt cabinet due to water damage that was hidden by strategically placed furniture.  

I am trying to think of a system that can work good for both sides, maybe something like a system where the PM will do a walk-through and get a detailed description including pictures of the items that need to be repaired, and then post a bid online so we can get multiple contractors involved in a bidding war, and I will be able to see the price without any markup or hidden commissions.

MF properties are the gem of properties for many investors, and as such they come with more competition, especially in this market.

That's a gem of a bank if you can get that for a rental property.

For example, the neighborhood I live in has horrible public schools and we pay a hidden tax called private school tuition.

Yes, I have been looking and seen a few gems there as well.

Make sure you don't have any issues with the condo, so you don't find any hidden costs.

Topsail Beach in Pender County is a hidden gem with ocean front under $500k.
