I do see lots of self storage and warehouses going up, so my default assumption would be that the old shopping malls do NOT trade for less than build cost, but it's possible that the marketplace is not perfectly efficient. 

No more going to three different stores looking for the perfect faucet!

They’re easy to install and, while not perfect, they’ll make a noticeable difference.

With Amanda Frecks as a partner and a clear plan for strategic improvements, it was the perfect fit for a quick flip and profit.

There is no perfect property. 

Hello,My wife and I recently found a property that fits all of the things we are looking for, perfect location, price, rooms, etc. except for one problem: The previous owner was a smoker :( Does anyone have experience buying/renting out/living in a home previously owned by smokers?

You will never have perfect knowledge.

Flips have done good not great, Air Bnbs are going good not great, and rentals all were brrrr'd perfectly but like most cash flow just enough to pay the bills and cover expenses.

No one is perfect though in RE if your doing volume your going to have a few that are bummers but at least in our program there is control.. not this feeling of helplessness when you hand your money over to a syndicate and they go dark your totally out of control of your funds..

It should be pretty accurate - high level data sites are not always going to be perfect, but should always be directionally correct and AirDNA has a pretty strong track record.
